Sir at 31:42... Shouldn't it be - y?..

@@wei_wei6741 it's actually -y he has considered q0 as +q/2. 1st option is correct

U left the question for HW but allow us to atleast have a look on the entire question. U just cover it.

The options given in the question in which we have to find the equivalent dielectric const. to be inserted, in that question none of the options are correct . U say its (D) but the option should be K= ----- but not 1/K= ----

Sir I am neet aspirant I know about you little bit late But I really love the way of your teaching Thank you very much sir.👌👌👌

[@aishwarysatpute7693]

We not experience teaching of avinash Sir before at vedantu. But got to tell you , you are great teacher........ Thank you for responding our request of modern physics. On video of 1lack subscription. Thank you a lot

[@ddwatcher]

the answer at 31:46 is -y because in question you said q0=-q/2 so the net force is along -y direction and displacement is in +y direction or vice versa. this is from JEE main 2013 . In original question q0=q/2 so y is correct but in your question as q0=-q/2 answer is -y

[@sanjivmohanty4270]

Exactly

[@physicsforeveryone1293]

Vector pada ha Kya ni Bhai , magnitude nikal rahe ha to sign ni rakhenge , agar q0= +q/2 hota to direction of netforce upward ho jate bas, answer wahi reheta

[@dhanajipowar5974]

Sir ,your teaching is soo good.👍👍👍👍

[@shamsulafaque3627]

That SHM question b should be the correct answer...... SHM..... a directly proportional to (-y)... Hence F also

[@jaii3119]

you're correct because (Q not) charge is (-q/2)

[@prashantmishra7507]

The way you say RIGHT is very cool and keeps us involved

[@ananthakrishnannair2780]

[@devanshtiwari9163]

In second ques why volume of sphere is taken 4πr^2 not 4/3πr^3

[@abhiroopghosal258]

because when you differentiate 4/3πr^3 w.r.t r, we get 4/3π(3r^2), hence we get 4πr^2dr

[@prithwishdas9054]

sir in the 2nd problem as ro is "r" dependent....so while integrating can we take them outside the integral?????

[@physicsnova969]

No 'rho ' is constant there .. because rho = charge/vol ....if r changes vol changes also charge but ratio b/n them always constant. So happily u can take rho outside of the integral .

[@anamikapandey1342]

Sir why the video is privated from today

[@adityaravindran8942]

In the second question, how do we know that the charge density itself isn't a function of r. Also the application of Gauss' Law is done wrongly here as that would work only if the distance between two adjacent equipotential surfaces is dr(infinitesimally small) and the question doesn't mention anything of that sort.

[@rajnisheng]

Sir in question 2 the volume of sphere should be (4/3)πr³ na And therefore the integration should have r⁴ na Please clear this sir

[@rajik4976]

Where do I get the solution of last question???

[@pratapsingh4598]

As I see it in the 2nd question charge density (rho) was also a function of r , how can u integrate r cube without even looking at the rho ?

Sir in the second last question the answer will be B for sure...D can't be the right answer. C1(dielectric constant k1) and C2 are in parallel and their equivalent is in series with C3... I'm 100% sure.

[@sudheerkumarchandrapalaka7592]

Sir pls teach previous yr advance pblms

Why there are many same problems which are discussed in all sprints??

[@srujanaevuram3782]

Last question answer is B

[@nilanjansengupta1866]

That SHM question you have shown needs attention.. the value of q0 is -q/2 not +q/2 so its proportional to -y not y ... or else how will it execute SHM ??

Chutiya hai kya bhai? SHM ka condition hi hota hai acceleration directly proportional to *negative* of displacement .... Magnitude mara raha hai..😂😏
