VITEEE 2024 Physics, Aptitude & English | Most expected questions & Top Must Do PYQs | Shreyas Sir

hello my dear J Warriors welcome to the vi e top questions pyqs of English aptitude and physics in this particular session I hope I'm Audible and visible to all of you do let me know quickly in the chat box yes perfect perfect so the session has just started this is your captain stas your physics Master teacher and uh like many of you know I've been sending kids every year to the topnotch colleges in the country this time will be no different so let's gather ourselves do not worry about your jmains percentiles put that aside move on and let's concentrate on all the other examinations which are at hand do not neglect any examination remember that you never know what might turn up you might get very good Branch by solving these questions you might be really happy in life so let's put all our sincere energy into this ready yes so vanam van come hello vishu hello Nani uh no VI is not better than nit definitely not like if you compare all the South nits like sural warangal even trii nagpur and all these obviously these nties are much much better but if you compare the low over lower nits then yes viit is much better so that is a reason why this is a very good private college okay so let's begin with our lecture let's begin with our lecture and uh here we go with the first section aptitude so I've kept aptitude first then physics and then English everybody ready for it now the aptitude questions usually are based on data statements relationships sequence series number magic uh magic boxes pattern identification these are the common kinds of questions you will get an idea uh you know seeing these questions here it is this is the first question what is the approximate percentage increase in the production of Ludo from 1993 to 1995 so you might be given a chart or a table and you will be asked to interpret it sometimes graphs are given sometimes spy charts are given Sometimes some analysis is given based on that you have to answer the questions are simple mind it but the timing is very important you should be able to solve these things very quickly now if you understand this question carefully from 1993 to 1995 the production of Ludo right you can see very clearly has gone from 150 to 195 so that is what it is so what is the percentage change it is 195 - 150 whole thing divided by 150 the whole thing multiplied by 100 so it is 45 ID 150 into 100 0 0 cancels 15 goes with 45 three times so that should be 30% just check this out option a very good ganeshwar awesome good morning good morning everyone uh balaj just refresh that should help you the video should not be stuck I mean just refresh that will be better okay have you refreshed all right okay very good right Vishnu will be providing you the answers and it is not important right now to do the J Mains last shift uh take we'll provide you the PDF don't worry about it okay we're doing the discussions mainly for the next shift people when there is nobody writing the next day because the questions are getting repeated I know you are also interested sir what were the answers that's why we'll be sharing the PDF is that okay cool move on now let's talk about the next exam what is the percentage drop in the production of lud from 92 to 1994 1992 to 1994 Ludo so how much has the percentage dropped by so from 200 it has gone to 180 so how much is the drop guys how much is the drop so 200 200 - 180 upon 200 into 100 how much is it 20 by 200 into 100 guys come on this is nothing but 10% just check this out option C for Captain Shas how many of you wrote C very good Trish I want everybody everybody to spam the answers because if you do not spam the answers that means you are going to take some time to solve it in the exam so even if you're wrong that's okay but I want you to spam the answers okay let's go on remember these questions you'll get 1 minute per question 1 minute per question as soon as you see it on the screen which of the following category there has been a continuous increase in the production over years continuous increase now if you see over here 180 to 175 there is a decrease not possible so Scrabble is gone Ludo also what about it uh from 200 to 150 so Ludo also is gone what about Chess from 100 to 92 it's gone what about caram also I think it is gone because 85 to 75 the only increasing trend is over here so I think Monopoly should be the correct answer how many of you have written Monopoly option b very good awesomeness let's find out yes it is correct let's go on to the next question let's see if you can answer this question is to identify the next number in the series The Usual trick is find out whether it is increasing or decreasing whenever it is increasing usually some multiplication and addition will be there when it is decreasing usually some division or subtra attaction will be there sometimes it can be Powers also Powers Plus something Powers minus something okay or some sometimes it could be multiplying with a ratio every time so try to fit in all the combinations which are possible here 285 253 221 189 it is definitely a decreasing Series so something should be uh either subtracted or something should be divided or you are taking out a certain digit reducing something most likely something like that so what do you think is the next number what do you think is the next number guys 285 to 253 253 to 221 221 to 189 are you seeing a particular thing between these two numbers when you subtract them what is the difference when you subtract them 285 and 253 so it is 32 it is 32 between these two if you subtract it that is also 32 between between these two also if you subtract it it is also 32 so between what and what the difference should be 32 guys 189 minus 32 it should be 157 I believe 157 option C yes it is correct option C 157 see questions are very simple but it has to be done under a minute that is the challenge students you know that's why mock test will be very very important many students look at VI Tri questions and they are like sir questions are simple I will crack it on the exam those are the students who do not crack VI e the problem is the speed the accuracy completion of the paper time management that's all moving on to the next one coming up on your screen in a certain code language presentation is written as something how would intelligence be written in that particular you know coded language you have to be very very careful over here now I don't see any usually what happens is p will be added by some two alphabets one alphabet or taken down by one or two alphabets but p and E are very far apart it's not even opposite like if it goes like this you go like that no because p is in the first n is in the last here e is in the first n is in the last I think I can see uh p r p r over here o n over here okay so basically I think the words are misplaced I can see some words are misplaced check this out PR is over here PR is over here then es s is over here es s is over here then check for en n en n is over here en n is over here then check for basically ta ta is over here ta is over here then check for TI t I is basically over here uh it is over here and o on o on is over here o on is over here o on is over here so this is the jumbling of words this is the jumbling of words the same jumbling you will follow guys the same jumbling you will follow over here so all you will have to do is do it in the same manner do it in the same manner that's it see when does it make sense see where does it make sense see where does it make sense that's it n and C is there an option many of you are seeing option D is that so just check it out the yellow has gone two on the second last side Lo has gone on two units to the second last side so I N yes I can see ion is over here the second last and green is over here the first green is here the first is it so yes the green is over here the first perfect then you should have orange over here you should have orange over here then the red one over here then the red one over here then the blue one over here the blue one over here and the last pink one over here just check if the same sequence is matching it is option D very good my dear Warriors that's it yes so it was just breaking it down into small small parts and arranging them and following the same Trend later on that's it it's the same logic okay moving on to the next one these kind of questions directional based visualization based questions Ram is moving somewhere north east west where is he finally from the original one yeah J 2025 also we will start my de Warriors after some time okay just give us some time we'll definitely start for all of you okay I know you you guys are eagerly waiting yeah the session will be for 1 hour something okay so for this particular question start drawing the diagram X he moves 20 M towards the North 20 M towards the north then he moves 40 m towards the West 40 m towards the West okay then he moves 20 M towards the north okay then he moves 20 M towards the north then he moves 40 m towards the east so he has come back on the same line okay 40 m towards the east then 10 m towards the right so as he's going like this 10 m towards the right means he has gone like this so if you compare from this point to this point how much will this be this is 10 this is 20 this is 10 this is 20 so the total will be 10 + 20 which is equal to 30 m North 30 m North should be the answer yes this is the final point this is the initial point so he is 30 m North how many of you wrote it option A many of you were saying C also or B also that is wrong it is not C it is not B my dear Warriors it is basically option number a right let's go on to the next one the fifth date of the month fifth date of the month is a Tuesday what date will be 3 days after the third Friday in the month quickly try to solve it under a minute the challenge is always the time remember that the fifth day of the month is basically the Tuesday so if you go back and see what are the other days 5 4 3 2 1 this is going to be Monday this is going to be Sunday this is going to be Saturday first is going to be Friday oh so this Friday is basically the first Friday when will the next second Friday be and when will the third Friday be think about it when will the third Friday and the second Friday be the second Friday guys come on 1 + 7 that is going to be 8th of the month and the third Friday is going to be the third Friday is going to be when guys the third Friday is when guys it is going to be 15th right so that is the third Friday everybody till this point is it clear everybody till this point is it clear very nice but the question is not that 3 days after the third Friday 3 days that means 16 17 and basically 18 so yes that is good going to be 18 just check this out everybody option D how many of you wrote option D very good answer is D yes cool Kudos the question could also have been what day it is what day is this so this is Saturday this is Sunday this is going to be basically Monday so that also could have been the question sometimes okay so just you know make a chart make a map quickly do the analysis draw it don't think mentally you might make mistakes always write it down okay there is no harm see it becomes very simple within a minute only you can solve when I'm explaining obviously I'll take more than a minute okay but when you're solving it in the rough sheet it will be very quick this is syllogisms syllogisms means statement based questions something is something something is not something all these things are these things those kind of questions are called syllogisms the way to solve syllogisms is always using when diagram when diagram like how you learned in sets makes it very easy some cats are dogs no dog is a toy conclusions are these which conclusions are always going to be correct some cats are dogs some of the cats are dogs this is a possibility some of the cats are dogs even uh no dog is a toy no dog is a toy no dog is a toy so this is possibility even the the second possibility is the second possibility is like this also also no dog is a toy you can see all the dogs and all the toys are separate all the dogs and toys are separate here some of the toys are cats these are possibilities I'm not saying this is always true these are possibilities now check it out some dogs are cats definitely some dogs are cats definitely you can see that some of the dogs are cats some of the cats are also dogs some toys are cats not always not always conclusion means always see understand what is the meaning of conclusion conclusion means is it true always is it true always sometimes it is true sometimes it is not true hence you will not make this as a conclusion some cats are not toys some cats are not toys sometimes possible some cats are not toys may be possible so this is not always true this is not always true do you understand it similarly all to are cats all the toys are cats definitely it is not seen over here so fourth is also gone so only the first conclusion is following uh the second and third one are wrong yes option A only conclusion one is true two and three are not correct okay sir why you didn't draw all toys are cats that's also possibility yes that is also a possibility uh what did you just say all all toys are cats all the toys are cats yeah that is also a possibility you can do it like this also all the toys are cats I can do it like this this is third possibility even I can do one more Poss there are infinite such possibilities I mean you can think about it imagine a set like this imagine a set like this this is the fourth possibility I'm just showing you few possibilities see to prove something you need to ensure all the cases are true to disprove something you just need to disprove one case how many of you understand this logic how many of you understand this logic whenever you have to prove something or to find the validity all the cases you have to prove not even one case you should leave but whenever you have to disprove something whenever you have to disprove something even if you disprove any one statement that's it the whole statement becomes false even if other statements are correct even if other statements are correct understanding this point so always try to find that case which makes it not uh which uh by which you cannot conclude it so I just drew some cases by which I cannot see the conclusion understood clear all right all right very good let's move on to the next one these kind of questions are also common now what does it say how is this hedge person related to this B person person H is married to p p is the mother of t t is married to d d is the father of b b is the daughter of t t is the sister of n h is the father of n but lot of people what they will try to do what is the relationship between H and B they'll try to find the relation no that is where you waste the time don't even have to do that look at the trick over here the options are only something else the option is not what is the actual relationship the question is is the data in this statement and this statement enough to find the relationship is this data and this data enough for me to find the or solve the question the data sufficiency question it is a data sufficiency question so check it out H and B we want to find H and B we want to find B is over here B is over here okay B is over here B is over here H is over here okay see quickly H is related to P okay p is related to T okay T is related to D okay and D is obviously related to B so indirectly H and B are related you can find the relationship done B is the daughter of T okay T is the do sister of n okay and H is the father of n n oh from B to t t to n n to h i can again find the relationship so both the statements lead us to the final answer so the data is sufficient so hence I think option C should be correct the data is sufficient can you see that the data is basically sufficient for both one and two both the statements the data is sufficient that's all it is not a is that okay everyone it is not option A my dear Warriors it is option D sorry option C cool shall we go ahead everyone everyone loving this session how many of you have liked the session already if you have not done that you are not doing Justice to the channel just quickly do that you're not supporting me I'll stop the series okay make sure you are liking the video yes liking the video and tomorrow similarly srj and today evening namata m is taking up the EAP St entrance examination Hot weightage Topics okay High weightage topics so make sure you are attending these lectures okay attend these classes this is very very important right for all of you moving on to the next one now we're going to go to physics so these questions okay be very quick in it all right let's see if you can be really fast we'll solve few physics questions just so that you get an idea of what level of questions and how fast you need to be light of wavelength this and this falls on two identical metal plates respectively the maximum energy of electrons is K and KB then which of the following is true Lambda a is 2 * of Lambda B so quickly use the photoelectric equation my dear Warriors so H C by Lambda a is equal to the work function and plus the kinetic energy of a then uh H C by Lambda B is work function work function plus KB now Lambda a is 2 * of Lambda B so from here k a will be nothing but H C by 2 * of Lambda b - 5 and from here KB will be H C by Lambda b - 5 - 5 so now compare these two now compare these two what do you think about this how are you going to compare these two k and KB how are you going to compare K and KB so I think the better relationship to do is make these two divided by two so that you can compare them divide this by two divide this by two now it is very easy to see now it is very easy to see compare Ka and KB just compare this term Ka and KB by 2 this term is same this term is same here minus 5 here - 5 by2 I'm subtracting more I'm subtracting less subtracting more means this is definitely less I'm subtracting less that means the whole quantity is more so so K is less and K B by 2 is more option A is correct option A is correct yes this is more this is less that's it option A how many of you wrote option A yes very good very good awesome my dear Warriors moving to the next question I'm not spending too much time on a question because that's how VI e exam is believe me and you need to get into that mode if I spend 5 10 minutes on a question you'll be like ah this exam is very relaxed no the exam is really fast let me tell you before you realize 2 and a half hours will be over it's not 3 hours it's two and a half hours and there are five subjects physics chemistry mathematics aptitude and English aptitude and English few questions are there but five subjects if you think of it psychologically okay which of the following curves represents the variation of impedence with frequency remember when you change the frequency there comes a point of resonance when impedence is minimum current is maximum and then again it increases so I don't think this is the graph I think it should be graph number c Zed minimum happens at basically resonance resonance exactly so how many of you have written down C for Captain STS how many of you written down C for Captain STS Anisha definitely there will be more classes for all of you definitely but it all depends on can you get your friends on this vant J English Channel do you feel that this is your channel do you you feel that when the subscribers on this channel grow sir this is for us only it is not for the sake of random things sir is not doing it for his own gain but for you guys okay my subscribers will increase my likes will increase what will I get from that am I going to get extra money nothing same salary only I'll get but the point is when many people like the session many people come to the session imagine the number of students getting benefited imagine the en of the teachers imagine the motivation of the teachers who will do more sessions for you that will indirectly benefit you only so understand it is only for you that I ask to like subscribe share comment nothing more okay because your marks are going to increase after one two we uh one two months you will be gone you will be you know in The Amazing colleges that you desired to be in understand that moving on carot engine takes calories of itat reservoir this gives it to sink at this work done by the engine is how much so my dear warriors uh you need to use the efficiency formula efficiency is 1 minus the cold temperature by the hot temperature is that right 1 minus the cold temperature by hot temperature everybody remembers this very good very good awesome now efficiency is also remember the work which is done upon the heat which is absorbed heat which is absorbed I think the heat absorbed is given work done is asked so work done is asked heat absorbed is 3 into 10^ 6 calories 1 calorie is 4.2 Jew so multip it by 4.2 right that conversion factor needs to be there is equal to 1 minus the cold cold temperature is 27 that means it is 300 kin this is a hot temperature which is 627 + 273 which is going to make it 900 my dear Warriors that's it so this is 0 0 cancel 0 0 cancel this goes with 3 1 - 1 by 3 is 2x 3 so therefore work done will be 2x 3 into 3 into 10^ 6 into 4.2 you can see 3 3 cancels 4.2 into 2 is 8.4 10^ 6 very very straightforward question very very straightforward question under a minute you can solve it yes under a minute you can solve it correct moving on to the next question on your screen now an element of this much length is placed at the origin which carries a large amount of current 1 m in the perpendicular Direction What is the value of magnetic field use your bio SS law it is nothing but mu by 4 Pi I DL right R sin Theta by R Cub this R cancel this will become r² this is basically 10 ^ - 7 current value current value is 10 amp the length is .5 then sin Theta is basically 1 because 90° whole thing divided by R square R is 1 M distance so 1 square so it will be 0.5 or 5 into 10^ something that's it option C how did I quickly say option C Guys Without Even calculating just ignore the powers of 10 decimals and zeros that is the trick what is the trick what is a trick ignore ignore decimals zeros and powers of 10 ignore them so whatever numbers are there just say five is the only number I can see so five is not there here five is not there here five is not there here this is 5.5 not five this is 5 into 10^ something directly Market that is the trick that is the trick everybody with me understood how many of you knew this trick this will save you some time in the calculations 20 seconds also if it saves it is a lot trust me in the uh srj vle like exams even bit set the flask contains monoatomic diatomic gases ratio 4 is to 1 mass of the temperature is this thing ratio of the average kinetic energy per the molecule of the two gases ratio of the average kinetic energy of the molecules is how much come on my dear Warriors average kinetic energy per molecule come on what do you think the answer is going to be what do you think the answer is going to be quickly put it up in the chat box their temperatures are same monoatomic and diatomic gases are there yes come on come on come on monoatomic and diatomic gases are there in the ratio 4 is to 1 by mass at temperature of 300 guys don't you see don't you see that per molecule the energy should be the same because the temperature is the same the kinetic energy the kinetic energy half m v² half M v² shouldn't it be the same it's just the average kinetic energy kinetic energy is half m v r Ms S half m v RM squ that's it so think about it this guy is nothing but rooot of 3 RT by m 3 RT by m indirectly it is only dependent on the temperature the temperature is the same it's just going to be the same it's just going to be the same if you don't want to look at it like that no issues the kinetic energy of a molecule remember and that to the translational kinetic energy we are talking about because it's not mentioned rotational so take translational so that is why it will be nothing but half KT there are three such translations so 3 into half KT isn't it directly dependent on the temperature temperature is same so it should be 1 is to 1 that is the answer that is the answer as simple as that no it is yeah it is not D Option 1 is to4 and all those things okay moving on next question my dear Warriors I want you to be really quick about this because that is going to give you the marks in VI e and I want every student to put in their 100% do not be demotivated by any of the percentiles sir you told the percentiles are going to be so bad and all of that forget it guys let's concentrate I want you to be out of this out of this 2024 right everybody has to plan to get into the college I want you to enjoy the freshers party of 2024 how many of you are going to enjoy the freshers party of 2024 in some college this year just put up a heart or a fire Emoji in the chat box quickly yes freshers party college freshers party amazing party guys it's going to be a lot of fun you're going to meet a lot of new people you're going to interact with so many so many people lot of cultural activities and so many developmental activities also so that is one of the first things that you'll do and so many clubs and so many things you'll get to know about the college right how many of you want to start that yes Telugu people raise the hand says Charan Tamil people also raise your hand Canada people also raise your hand anybody else also raise your hand very good awesome SSN entrance my dear Warriors I'm not so sure okay cool uh see the uh in the previous question don't count the total degrees of freedom when you just say kinetic energy it means translational kinetic energy so only count the three translational degrees so be it mono or be it Dia there are always three translational degrees two additional rotational degrees are there which you will not count okay so keep that in mind that is a tricky question yes the correct answer for this is option a half K x² you can put x - A that is just shift of origin that's okay what is this cubic equation exponential equation constant equation it is a quadratic equation if you remember potential energy it is always a parabola Parabola so it has to be a quadratic equation quadratic equation not a cubic exponential or a constant equation as simple as that try to solve this question my dear Warriors come on come on come on come on my dear Warriors let's figure out this answer as well electric field is in which direction it is in the X cap that means uh x- axis it is like this the question is the flux through the Shaded area as shown in the figure due to this particular field is now if you look at the coordinates now you will get lot of confusion I'll tell you it is basically slanting it is basically you know slanting in nature so so you just think about the electric field which is going to be parallel to the x-axis it will be like this so divide the area into two components one is going to be like this one is going to be like this and the second one is going to be like this how many of you are able to visualize this now sir yes sir I'm able to visualize this now how many of you are able to visualize this now I have divided the area into two parts so how is the field going the field is going along the x-axis so it is going basically like this piercing through the green area not the red area so ignore the red area what should be the green area my dear Warriors what should be the green area think about it quickly and answer the height will be a the base will be also a so the area area will be a square what is the electric field my dear Warriors it is basically e so what will be the flux IDE Warriors it will be field into area so e into a squ option C yes that's it option C correct very very straightforward very very straightforward isn't that right everybody so these are very direct questions if you visualize it like this it becomes so ladu otherwise it is very difficult why we didn't take the red area because for the red area understand the electric field lines are going like this they are not pierc ing through it so that is why no flux no flux for the red area and can I split area into two components yes because area is like a vector quantity so that is the reason why I split it into two parts if you're wondering about it equation is given wave of the wave on the string of linear mass density blah blah blah question is what is the tension in the string all right my dear Warriors for finding the tension what do we need uh this formula V is root of T by mu so tension is v² into mu V I don't know but U is mass per linear mass density which is given to be 04 what is the speed well to find out the speed look over here the speed is the coefficient the coefficient of x upon the coefficient of time what is the coefficient of x it is 1x05 what is the coefficient of time it is 1 by 04 so uh it will just become 4X 5 so just put four over here and just put five over here that's it so the answer should be uh 6.25 Newton 6.25 Newton but this is square of course this is square of course that's it option D everybody clear everybody clear awesome awesome yeah hey who is this waste fellow some girls are there it seems oh get lost man what kind of nonsense is this at this point of time you are interested in all these rubbish activities focus on the class H 1 by5 oh I put oh sorry sorry sorry sorry I put 05 so sorry let me change it let me change it it is5 so sorry so this will basically also change I'm so sorry this will be 0.04 / .5 so shift it so it will become 40 by 5 two decimals okay two decimals over here sorry not 40 4 by 4X 50 right that's all I have done so put 4 ided 50 over here and then Square it is that okay fair enough all right okay shall we move ahead Pine I'll be starting the J Advan classes also very soon very soon just give me like one two days okay I'll be starting okay just hold on moving on the equip potential surfaces are shown the electric field strength will be how much 10 volts 20 volts 30 volts so where does electric field go electric field goes from high voltage to low voltage high voltage to low voltage that means the electric field should go in this particular direction always from high to low okay electric field is along x-axis wrong electric field is along the y- axis wrong it is at a 120° angle with the x-axis yes most likely 120° with the xaxis most likely so I do not know whether it is option C or option D But A and B are definitely wrong so how do I find that how do I find the strength so basically just see what is the distance between these two lines what is the distance between 10 volts and 20 volts line just drop a perpendicular so the base is let's say 10 units this this this is perpendicular this is distance this is 30 ° so how much is this distance this will be 10 sin 30 which is basically 10 into half which is basically five so this is 5 m and remember electric field is in this direction electric field is in this direction and electric field is Delta V by delt R Delta V is the change of the potential which is 20 - 10 and the distance is basically 5 so it is basically 10 by 5 uh but that is in cm so convert it into meters remember this was centim so into 10^ minus 2 it will become into 10 the power + 2 so this will become basically 200 so hence option C should be correct yes option C is correct option C is correct got it my dear students everybody with me on this cool let's move on to the next one coming up on your screen water is falling from some height and the question is basically what amount of of hydroelectric energy can light up how many number of lamps how many number of lamps can you light up okay that is the that is the question 50% of the energy is only converted so per hour so first of all potential energy potential energy okay is nothing but MGH H MGH so potential energy per unit time is MGH H by T the electrical energy which is coming per unit time is half of the total potential energy per unit time so it will be basically half of MGH H by T this is the electrical energy per unit time which is also the electrical power which is also the electrical power the question is how many 100 watt lamps can you light up each lamp consumes 100 watts each lamp consumes 100 Watts multiplied by n will give me the total electrical power which is exactly this which is half MGH h / T So 100 * n is equal to mg H BYT so here we have all the data points like the mass is given how much mass 9 into 10^ 4 kg per hour 1 hour is 3,600 seconds gravity is 10 height is basically 40 and this is into n and this this is 100 from this you will get the value of n check it out if it comes out as 50 check it out if it comes out as 50 okay in fact you can see 9 4 are 36 36 36 cancels half is basically .5 all other are decimals or powers of 10 or zeros so answer should be 5 into 10 the^ something so it is 50 directly also I can mark it by using my trick of ignoring the powers of 10 ignoring the powers of 10 moving on to the next question guys coming up on your screen the electron moving with the speed of this enters a magnet field if it describes a circle of this the strength of the magnetic field must be direct formula r equal MV / QB therefore magnetic field is equal to MV / QR so mass mass mass mass electron is close to 9 into 10 ^- 31 velocity is 10^ 6 uh charge 1.6 10 ^ -19 and mag and the radius the radius is basically .1 my dear Warriors that's it solve this and see what is the answer that you are getting close to 5.5 into 10^ minus 5 Tesla direct usage of formula many of you are wondering sir how did I get this value you should remember these values mass of electron mass of a proton right atomic mass unit standard mass of Earth all these values better remember it sometimes they might not give it and you cannot cry you cannot cry that sir uh this was not given that was not given you cannot cry for that it's not like NTA NTA is one body which at least listens to you okay we can make videos we can do this we can say like please NDA please don't do this and they listen see last uh January attempt whatever mistakes they did they did not repeat it this time so hopefully the percentile distribution will be much more even but in V you cannot do anything it's done it's done that's it it's a private college so V1 is a velocity of the body from point A V2 is the velocity of the body from point B which is vertically below the highest point C both the bodies collide then if both the bodies are Collide that means the time to reach on the top will be the same isn't that so the time to reach on the top will be the same correct so what will you do my dear students what will you do just think about it just think about it there vertical component should be same if their time to reach on the top will be same their vertical components are same yes this guy also has a horizontal velocity which is bringing them closer but since their vertical velocities are same they're able to reach at the same time so V1 sin 30 sin 30 will be equal to V2 sin 30 is basically half so that is the relationship so V1 is 2 * of vs2 V1 is 2 * of V2 so the time is same the time taken will be the same so the vertical velocities are also the same that is the idea used here okay directly solve the question Cool let's go on to the next one one coming up on your screen there is a frame 10 cm at some distance beside a wire question is if the wire is drag sorry if the loop is dragged how much EMF is generated okay first of all let me tell you the formula for EMF is lvb lvb correct and EMF is only generated if length velocity magnetic field these are perpendicular so here if you notice the velocity and the length they are all in the same direction so ignore this part and ignore this part no EMF generated here no EMF generated here whereas over here there will be some EMF let's say E1 generated there will be some EMF E2 generated both these emfs are opposite so the net EMF the net EMF will be E1 minus E2 E1 minus E2 because 1 EMF will be clockwise 1 EMF will try to provide the voltage anticlockwise so since it's like two batteries connected in the opposite directions in series so you will take the net EMF as the subtraction of their emfs and each EMF will be length into velocity into the field and length into velocity into the field length is same velocity is same magnetic field is different because the distances are different so length is same velocity is same magnetic field is different what is the magnetic field formula it is Mu I / 2 pi and the distance let's say X1 minus mu I / by 2 piun X2 so this will become nothing but L into V into mu / 2 piun and then there is I also here you have 1X X1 - 1 by X2 that's it you know all the values over here here after this you know all the values the length is basically .1 M the velocity is nothing but how much uh 10 m/s mu by 2 or mu value you know is 4 Pi into 10^ - 7 the current value also you know is 1 ampere it is 1 amp then X1 and X2 values well this is X1 X1 is how much 10 cm that means .1 M X2 is this much X2 is this much it is .1 + .1 which is2 M that's it substitute the values you will get the answer as 1 microvolt you should get the answer as 1 micro is that okay everyone so this is a lengthy question in in case of examination you will leave this question okay and try to solve it at the end try to solve it at the end do not keep it in the between in fact there is a easy way to eliminate two options how many of you know this trick do you want to know the trick even without solving these things I have a 50% chance of getting the correct answer answer I have a 50% chance of getting the seven correct answer how many of you know this trick do you want to know the trick thank you pranu yadav love you too my dear Warriors always sayi what is a trick yes time consuming question that's why you leave it but you'll solve it at the end and if there is no time what will you do you have to guess how do you guess Simple Thing check what is the highest value check what is the highest value in the options don't even read the question I'm just looking at the options highest value is this check what is the lowest value check what is the lowest value it is this so ignore this and ignore this it will be either this or this it will be either this or this so you have 50/50% chance 50% chance is better than 25% chance out of four options picking one option is better than better than picking just one out of two right understood my dear Warriors yeah if the magnetic field was constant then there will be no EMF your magnetic is different that is why there is EMF which is generated right so the magnetic field is different because of the distance relationship understood this trick loved this trick smash the like button if you have not done that okay capacitor and inductor in parallel applied to a uh AC circuit the question is what is the current drawn from the generator here the current through the what is it condenser means capacitor is basically point4 current through the inductor inductor is9 I have seen a lot of people what they do is they add these currents 4 and 0.9 but that is not the case they are in parallel when you are in parallel the voltage is the same the voltage is the same so unlike series circuit where you draw on the horizontal line the current here you will put the voltage and the current will be you know like this and like this remember for the inductor the voltage is ahead of the current so I will be here and the inductor volt current is .9 and for the capacitor the current is ahead of the voltage so here you will put IC as4 now this is the correct way of drawing it now you can see that the total current is not IC plus I rather it is I minus IC by phaser by phaser diagram so it is basically .9 -.4 which is .5 amp so it is5 which is option see this is a very tricky question many students make a mistake here oh you are in class 8 wow welcome Young Warriors why did you eliminate options Karthik that is the psychological effect of an examiner when they set the paper what if your answer is let's say five they will always try to keep two more options one lower or one upper you imagine you are the paper Center you want to create options that is human psychology human behavior is predictable understand that and psychologists have done this okay so there is a very good chance I'm not saying always there will be obviously somebody who will beat the metrics but most of the people will follow certain things so we we know that these Trends continue nobody applies so much brain that okay some teacher s is there into existence and he's teaching these tricks to the students these are the cheat codes which St s is giving to the students so I will play and make the options in a different way they don't know about all this they're just going to make the options using normal human psychology and I know that right so that is why I'm telling you this oh thank you mitochondria mitochondria is also here the power of of the cell wow very nice okay what about this the ozone layer in the atmosphere absorbs how much the ozone layer in the atmosphere absorbs how much come on my dear Warriors what does it absorb what does it absorb come on quickly tell me yes the answer is D xray is an UltraViolet rise so our skin gets protected UV ray so ozone layer is meant to absorb all x-rays as well as ultraviolet rays that is a fact you should know it if you don't know it now you know and don't make the mistakes young slit experiment how many Maximas can be obtained on the screen including the central Maxima both sides Central Fringe blah blah blah Lambda is given D is given okay Lambda is 3,000 and D is 5,000 Lambda is 3,000 and this is 5,000 what do you do in these cases first of all always in these questions find the ratio of d by Lambda find the ratio of d by Lambda D is basically 5,000 Lambda is basically 3,000 blah blah blah blah blah blah so 5x3 okay so D is basically 5x3 * of Lambda everybody till this point is it clear okay now we know that 5x3 will be approximately like 1.67 * of Lambda that's enough for me what you should do is quickly draw a line quickly draw a line mark one first line over here and call it Z Lambda the question is on both sides how many Maximas Maxima means the part difference is integral multiples of Lambda integral multiples of Lambda so 1 Lambda then 2 Lambda then 3 Lambda yes here also 1 Lambda 2 Lambda 3 Lambda but when is 1.67 Lambda remember remember this your path difference has to be lesser than has to be lesser than 1.67 Lambda it can't be more than that so if this is the criteria then this is allowed this is allowed this is allowed this this this this is not allowed so totally three Maximas are there that's all that is the easy trick to solve these questions easy trick find the ratio of d by Lambda see what is it okay once you get that number just write 1 Lambda 2 Lambda 3 Lambda 1 Lambda 2 Lambda 3 Lambda all those numbers below this are allowed for Maximas all the other numbers are not allowed okay okay Malik Arjun do you want me to give cheat codes for Vi how many of you want me to give cheat codes how many of you want to increase the marks yeah and do you want us to come to Chennai also also for your counseling do you want us to come for your you know your career guidance maybe just for a few hours do you want to meet me I want to know after your VI exam I will come no issues after your srmg exam I'll come after one two weeks is that okay we want to yeah meet us counsel guidance click photographs maybe yeah okay but main thing is Sir what to do for J Advance sir what to do for bitet sir is this college good should I take a drop should I not take a drop do you want us to come Chennai madurai and uh maybe kbat and if if time permits maybe one 3 and Salem hopefully Salem is my birthplace yeah madurai how many of you are from madurai Chennai I live in bangaluru yeah Salem also I want to come Andra Andra I was there just few weeks back I was there in Andra Hyderabad was there in Hyderabad yep I'll come to Hyderabad again and maybe even Viada okay force between two identical short bar magnets whose centers are armas this this this the separate is increased to double the force between them is reduced to how much okay so my dear students in this question what you will do is Remember the force between magnet and magnet is actually inversely proportional to R 4 so if I double the distance this will become 2 4 which is as good as saying into uh basically 16 times so 1 by 16 times so the force will become 116th of the older Force of the older Force so that is .5 Newton so5 Newton is option C yeah R to 4 that is the answer be we very very careful it is R ra to 4 not anything else correct oh Ashu my bad I always keep thinking Hyderabad is in Andra okay it happens psychologically you know because I was born at a time where Andra and Tana were one yeah so I naturally think of the same yeah but I know it is in telana cool anyways what about this R for scattering experiment in the projectile of charge zed1 and mass M1 approaches a target of Z2 and mass M2 the distance of closest approach the energy of the projectile guys and uh what happens is when you talk about the distance of closest approach the kinetic energy gets converted into potential energy from the target nucleus Target nucleus Target nucleus is Z2 this is basically Z1 this is your closest distance so that kinetic energy becomes equal to the potential energy potential energy is 1x 4 Pi Epsilon charge 1 which is Z1 into e into charge 2 which is Z2 into e upon basically R squ so you can see it is directly proportional to the product of Z1 Z2 Z1 Z2 is the product so hence that is the answer option a directly you can say that everybody with me got it yeah awesome awesome awesome very nice very nice moving on to the next question guys coming up on your screen what will you do in this particular question quickly tell me what's the maximum speed of the car on the road turn radius 30 m coefficient of friction okay the maximum speed formula for a car turning around a road is Mu RG so question is what is the maximum speed mu is basically point4 R is basically 30 G is is basically 10 so 10 into 4 is 4 4 into 30 is rooot of 120 now root of 120 guys what will it be root of 120 close to 11 121 is close to 11 so it should be option A don't sit and calculate sir what is root of 120 120 121 Clos 121 is root 11 11 is close to 10.84 so that should be the answer directly move on next question on your screen person coming to reach exactly the opposite point on the bank of the stream is with a speed of5 m/ second at an angle of 120° with the direction flow of the water the speed of the water in the Stream is okay so over here let's draw the river banks tries to reach aiming the exactly opposite point is swimming with a speed of point at an angle of 120 with the direction of the flow of the water the flow of the water is like this 120° means here so he tries to go like this with how much speed .5 m/ second so 120° this is 90 so naturally this is 30 and the flow of the river will be like this this is the water velocity the resultant velocity will be like this so that he ends up reaching here that is the diagram the speed of the water in the Stream in this particular question the diagram which I have shown uh s of 30° is the W by hypotenuse so w will be .5 into sin3 which is half which is 1x 4 which is .25 yes perfect that is the answer that is the answer once you draw the diagram it becomes very very L very very L okay is that right everyone all right moving on to the next question coming up on your screen here it is a car which is going at 20 m/ second Bank track describes the circle of radius 40 root3 the angle of banking is okay 20 m/ second on a bank trap and describes an arc of a circle this much the angle of banking so if it is banked for this particular speed the the speed formula with angle of banking is given by V is root of RG tan Theta RG tan Theta V not is 20 radius is uh 40 < tk3 G is 10 tan Theta I do not know Square both sides 20 square is 400 is equal to 40 < tk3 into 10 into tan Theta 400 400 cancels root3 comes over here so it will become 1 byun3 is tan Theta so whose tan is 1 byun3 it is 30° yes option b is correct option b is correct everybody cool yes quam quam Arjun okay very good shall we move ahead to the next one here it comes force acting at a point the value of alpha for which angular momentum is conserved so if angular momentum is conserved that means the net torque is zero that means r R cross f is 0 so if R cross f is 0 that means the uh ratio of the coefficient should be similar that means Alpha by 2 should be equal to 3 by - 6 which is equal to 6 by -12 you can see the ratio is min - half the ratio is basically minus half because if this is true that means R is parallel to f r is basically parallel or antiparallel to F so right so hence Alpha will be 2 * -1 by 2 which is -1 so Alpha is min -1 oops option D is given I think it should have been uh yeah option number B option number B okay I think there is a printing mistake over there yes because the number should be exactly opposite if this is minus this is plus so Alpha is minus then 2 will be basically plus yes is that right okay moving on to the next one coming up on your screen convex length is broken down into so and so Parts question is what is the power of each lens what is the power of each lens come on my dear Warriors what is the power of each lens come on let's see if you can solve this the when you break it into two halves like this like this then each will be P by 2 p by2 when you break like this the power does not change it will be p and p only come on my dear students what should be the correct answer now power of lens one is uh oh but be careful incorrect options are asked incorrect options are asked so power of lens 1 is p by 2 No it should be actually P so this is incorrect I think rest all will be correct only then rest all will be correct lens number two is p by2 yes this half yes power of lens number three is also P by2 power of lens number one is p yes option A is definitely wrong in fact you can see these two options L1 is p by2 L1 is p so one of them has to be wrong so when incorrect question is asked don't even focus on B and C directly Focus On A and D because one of them will have to be have to be wrong next one this ball falls down the question is if the velocity of the ball does not change on entering the water the viscosity of water is EA then the value of height is given to be okay so it falls down falls down and whatever speed it gets the speed remains constant that means it should be terminal speed and the speed with which it collides the speed with which it the speed with which it falls for a free fall is given by the formula root of 2 G root of 2 G terminal speed formula is 2x 9 G r² Sigma minus Row the whole thing divided by e solve this you'll get the answer just Square this off so 2 GH is equal to this whole thing Square 4 by 81 g s r 4 ETA s Sigma minus row and all of that so solving this you should get the answer as option C yeah you will get the answer as option C is that right everyone okay you can see that understood clear very good very good it's straightforward question straight forward question moving on to the next question in fact yeah what is it a given ray of light suffers minimum devation in a equilateral prism additional prism q and R of identical shape and material are now added to P then the ray will suffer same deviation greater deviation no deviation total internal reflection this this and this are identical so imagine only when uh this prism was there when the prism number P was there the ray of light was entering and having some deviation when p and Q will be there when p and Q will be there think about it when p and Q will be there that ray of light will not suffer only any deviation it will basically come out parallel to it now once it has come parallel to it the single the single uh you know prism of R which is there the single prism of R which is there the light will enter and undergo the same effect what P did whatever happened with P the same effect will happen with one single uh prism of value R so the first two prisms are basically cancelling out each other the third prism is the effective prism so it will behave like the original prism so there will be no change or basically the same deviation will happen the same deviation as before will happen is that right there will be no further change of deviation understood okay okay so the first two prisms canceled out so effectively three prisms is like one prism that is the whole idea so the same deviation will happen like before next one if m is the Magnetic Moment B is the magnetic field then the torque is given by come on torque is nothing but Magnetic Moment cross B that's all direct formula based is it not option C M cross B how many of you got it very good okay very good very good very good good awesome awesome awesomeness very good very good option C moving on to the next one coming up on your screen Planet at certain distance solar system is 10 times more massive than earth and its radius is also 10 times smaller given the escape velocity of the Earth surface is this the escape Velocity from the surface of the planet will be how much escape velocity is given by the formula root of 2 GM / R now what happens is uh this is 11 km/s for Earth so for that other planet I don't know the escape Velocity I will call it as V2 but it is clearly mentioned that the mass is 10 times more and the radius is 10 * less so it will become so the uh value will become root of 2 GM / R and 10 into 10 will become basically 100 so 100's root is basically 10 100 roots is basically 10 this value is 11 so it will become 11 into 10 which is 110 that should be the answer yes option C yes option C directly you can get it no it is not a it is option C many people cancel the 10 and 10 and they say Sir the answer is same as before and they say it is option A no you missed it it is smaller it is smaller and bigger so you know it will multiply 10 into 10 so it will become basically like this root of 2 g m / R 10 into 10 so root of 10 into 10 will be 10 outside the root got it okay moving on okay some homework questions for all of you you're going to take a screenshot of this and also this this is your second homework question okay just solve this let's solve some English questions quickly ready for English full with Jo if you are new to the channel have you subscribed a Willers will be starting very soon yeah ready for English oh did I miss that gravitation part yeah when come chandu when come yep let's let's let's do it yeah last 5 10 minutes of the class starting off with a passage question this passage question please take a screenshot if an opinion contrary to your own makes you angry then this is a sign that you are subconsciously then you are subconsciously aware of having no good reason for thinking as you do but if someone maintains that 2 and two are five or that Iceland is on the equator you will feel pity rather than anger unless you know so little uh of arithmetic or geography that his opinion shakes your own contrary conviction understood the passage or did it go bouncer sir what is this passage sir okay tell me quickly understood this passage okay keep this passage on your screen maybe on the side or something take a screenshot here is the first question if someone else's opinion is making you angry what does it mean what does it mean my dear Warriors we are subconsciously awaring aware of having no good reason for becoming angry there may be a good reason for his opinion but we are not consciously aware of them our own opinion is not based on good reason reason and we know this subconsciously we are not consciously aware of reason of your own opinion very confusing options go back if someone else's opinion makes us angry it is a sign that subconsciously you are aware of having no good reason for thinking you're subconsciously aware of you know no having no good reason for thinking whatever you are so your own opinion is not based on a good reason and we know this subconsciously I think it is option C just check this out yes it is how many of you wrote C A what is this a MH no no good reason for becoming angry that's wrong in the if it makes you angry that is a sign that subconsciously you are aware of having no good reason you're not subconsciously aware for becoming angry no this is not right this is not right you're subconsciously aware that okay I don't have any good reason I don't have a logical opinion to counter the other person so option C is more appropriate be very careful yes yes understood clear perfect okay so what does this statement mean your own contrary conviction your own contrary it's like oppos posing come on what does this mean conviction means something what you believe in the fact that you feel pity rather than anger the opinion that two and two are four the opinion that two and two are five the fact that you know so little arithmetic or geography your own contrary conviction the fact that you feel pity rather than anger I think that was there in this particular passage if you know for your own contrary conviction right you will feel pity rather than anger because you believe in something okay but you know that it is not right it's opposing what your belief is so you know this is what the correct option should be where is it option number a the fact that you feel bitty rather than anger yes awesome awesome what about this conviction conviction means lot of you were thinking sir what is this meaning of conviction I'm convicted of the I'm I'm convinced so it is derived from that conviction means it's my strong belief so I think option C should be correct strong belief my conviction is that I can crack J my conviction is that I can crack this entrance exam that means you believe it so contrary conviction means not what you believe in it's opposing what you you believe in okay the writer says if someone maintains that two and two or five you feel pity because you have sympathy don't agree with him want to help the person feel sorry for his ignorance this is straightforward why do you think you will be pity rather than being angry rather than being angry come on think about it because you know that the person is wrong and you are aware of the true facts then you're feeling sorry that he does not even know anything that's why not because of sympathy as per the writer so feel sorry for his ignorance correct very good very good moving on to the next one the second sentence in the passage means what let's go back to the second sentence in the passage the second sentence in the passage this statement if someone maintains that two and two are five or Iceland is on the equator you will feel pity rather than being angry unless you are knowing very little about geometry arithmetic geography uh which will shake your own contrary conviction so what do you think the correct answer should be just check if it is illustrates the point made in the first statement yes correct builds up the argument of the first sentence by reciting it from the opposite point of view no it is basically demonstrating whatever the first line meant the first line was exactly you know an opinion which will make you uh you know angry it's a sign that you are aware you are not having a good reason when why are you becoming angry because you don't know how to counter that argument to demonstrate why you become angry and when you don't have a reason this second statement is explaining that is explaining that you will become angry because you don't know that subject you don't know the logical reasoning for it you don't know how to counter that that is when you will become angry else you'll feel pity that oh this person does not even know this maybe he is not aware of these facts so that is the reason why the answer will be uh you know option D now remember the vi e test series are available in the description box right for just 4.99 rupees original price was 999 rupees 50% discount straight off with six full syllabus
