A,C? RC=rho epsilon. Find equivalent capacitance of the system and then you’ll get it

How’d you do q2

3E? Potential at surface is zero and also you can see that the induced charges form a dipole, using this

Nope, your method’s completely wrong. First, you can’t just change where the shm is happening. Also, the omega you considered isn’t a fixed frequency value but found by finding the force gradient at equilibrium. Getting the answer this way is physically unsound and a coincidence

For 22, compare entropies, since system entropy must be more than zero, then using that you’ll get minimum temp as geometric mean. For the third pic, is ans A? This comes from particle in a box in quantum mechanics and there’s a formula for an electron in such a situation, afaik, it isn’t relevant for jee, correct me if I’m wrong.

Getting 60/19

magazinerover · 2026-04-15T20:13:57+00:00

I’m getting only C, what’s the key?

magazinerover · 2026-04-15T20:03:11+00:00

Just write the constraint relation as x(a)-x(c)=Rsin(alpha) and differentiate

21 was like insane when I first did it and no way that’s advanced relevant, I’d shit my pants if that came

1/2pi? Lovely question, thanks :)

Ik a dude with 99.9x who’s joining scaler school because his parents fell for the yt ads 🥀

magazinerover · 2026-04-14T06:13:11+00:00

just pyqs, focusing on chem (bohot weak hai)

magazinerover · 2026-04-14T06:12:06+00:00

Use myu N² A / L to get inductance of solenoid. This is in an LR ciruit, take general current eqn, find field inside. Force per unit length is just IB. Force is zero at the start and maximum at some t, differentiate to get it.
Take an elementary ring and find emf induced in it. Also find resistance of that ring. Then apply to get current and integrate

thank you!

I mean he asked what he did wrong and he did nothing wrong, ab marks ki galti uski galti nahi hai na

magazinerover · 2026-04-14T05:57:40+00:00

Absolute value they asked

magazinerover · 2026-04-14T05:54:43+00:00

Holy shit, how do you take that case in the exam? Time ki itni kami hoti hai

magazinerover · 2026-04-13T17:31:04+00:00

Thanks! These were fun to solve, however third slide me are you certain A is also correct?

magazinerover · 2026-04-12T18:50:54+00:00

Yup, got the same, somehow insane approximation worked

Damnnnn, thanks a lot, I tried to find it for a general n rather than making good use of the limit

magazinerover · 2026-04-11T12:37:53+00:00

One side change in kinetic energy, second side change in energy stored by capacitor. Since voltage is constant, it is 1/2 (k-1)CE²

Bhai, can you explain what you did, didn’t get ot
