  4. sir no doubt that the above question is a bit tricky so with the help of ur lecture i understood it and the same way i inculcate and i will apply in questions i face of similar kind but if we see previous years iitjee questions they are no doubt tough but also more tricky..though we know the concepts properly and efficiently we are unable to solve previous years questions by ourselves or in one or two attempts also we arent getting them but when we see solutions its like ohh i missed it here...soo could u please tell me what i lack in either concepts or clarity or anything that is causing my failure??????????

  6. Sir I would appreciate it if you would upload a motivational video to help students to prepare for IIT that contains: - Getting out of materialistic desires that would turn our lives to dust - Distractions that would destroy us for sure There are MANY friends who were intelligent but due to their pull towards desires like smoking/drinking they are now suffering! sure they may sometimes look happy! but behind their faces inside them lies a big sad person that always wished to return back to the past and change their habits. It melts you down to see such people suffer! People may say that smoking/drinking is a bad addiction! but... the BIGGEST AND MOST COMMON ADDICTION OF ANY STUDENT IS TOWARDS SEXUAL PLEASURES! But NO ONE talks about it (except... my english teacher... thanks to her I chose the better path) But there are many people out there who have potential to do something GREAT in life! But they get trapped by their own desires! For a person... STUDENT to study... he must have the ability to see what is the TOP PRIORITY! but there are people who can not take the decision! their young enthusiastic genuine brilliant side slips off from their grasp and dies off because NO ONE SPEAKS ABOUT THAT!!! So... I just used this opportunity to speak my heart out... I'm sure you know what we students are going through.... I THANK YOU FOR TELLING WHAT EXACTLY HAS TO BE DONE BY A BRILLIANT STUDENT!!!!! but likewise please o please make videos.... for telling us WHAT NOT TO DO!!!! I would very much appreciate it! PS. This is a message from a BIG GROUP!

  8. Sir plz help! plz reply... (doubt asked at the end of this comment) if I use the equations from ground frame I get: Y=height gained by balloon= 125 + 25t (I consider an equivalent problem where at t=0 the balloon has gained a height os 125 m) and y= ut-5tt Also I put v=final velocity of bullet=u-10t Now if I assume that the bullet hits the balloon with 0 velocity then the y displacements of the two moving bodies equalize to give Y=y at a time t when the final velocity becomes 0. From third equation 0=u-10t; u=10t Putting it in equation Y=y we get 125 + 25t = 10tt - 5tt which gives t=2.5(1+sqrt(5)) s here u = 10t = 25(1+sqrt(5)) m/s which is completely different from the solution withe the shifted reference frame... so questions 1) is the above solution wrong? question 2) if the answer to question 1 is no... then why do the values not match? if yes... where have I gone wrong?
    4 months ago by PSai Krishna Kvmb
    Ans 1 ->
    Your Mistake - you equated the y displacements of both at zero final velocity that is not the case... For minimum initial speed y displacements should be equal when the bullet speed is 25m/s as after this instant bullet speed decreases and it cannot approach the balloon... think again and resolve with your method...

  10. explain what makes it wrong if coulomp's law for the force between two charge is written as F = k/r^n with n not equal to 2
    6 months ago by rohit purohit
    Ans 1 ->
    In that case the field in surrounding of charge will be become inconsistent... and Gauss's Law will become invalid... as the flux varies with change in shape of surface not only be dependent upon the enclosed charge...

    8 months ago by Anupam kumar
    Ans 1 ->
    For theory these lectures are sufficient including advance illustration videos... but you need to do regular practice to gain command over problem solving to achieve a good rank as time management in solving problems is also a main factor...

  14. Sir why was the balloon taken to be at rest when we know it is still ascending and how does speed of bullet becomes u-25
    9 months ago by Siddhant Mahapatra
    Ans 1 ->
    This is a way to solve the problem using relative motion, its better you first read all videos in sequence of the topic relative motion and attempt qusets before following adv illustrations...

  20. why didn't we take g as negative in final step of solution??
    1 years ago by Ramesh Agrawal
    Ans 1 ->
    see its actually v.v-u.u=(-)2gh....this is the actual formula where it is taken negative but observe properly u-25 is the intial speed which means (U). so it becomes(-)u.u =(-)2gh.....(-) gets cancelled and we get the final step..cool brother ur doubt is correct but remember to make ur basics pillar more strong before coming to adv illustrations i didnt mean u arent fit for this but i meant its more good if ur basics are more stronger

    1 years ago by mahendra choudhary
    Ans 1 ->
    no it will not change as perpendicular distance is same at every time.from origin.
    1 years ago by harshit
    Ans 2 ->
    No.The perpendicular distance between the linear momentum vector of the mass and the origin remains fixed as the mass moves parallel to X- axis with constant velocity.

    Ans 3 ->
    |delta v | = ( v1^2 + v2^2 - 2v1v2cos0 )^1/2 = 2^1/2 * v .So answer is 50 (2)^1/2 where v1 = v2 and 0 = 90 degrees .

    Learn physics with real life situations.Try to explain simple phenomena around you with your current knowledge in physics.If you fail try to gather that knowledge.In applying physics imagining the outcomes is of utter importance.To strengthen this statement remember the quote of Einstein that 'imagination is better than knowledge.'
