How was physics 9702 p41 ???

Aight .. to get 3Q (additional charge) u first have to find the charge when the sphere has a radius of 52cm which is 6*10^-6 C and the Q (sphere with 28cm radius) was 1.5*10^-6 so to find the additional charge u have to subtract 6-1.5 which is 4.5 *10^-6. And then divide it by Q (which is 1.5*10^-6) so you’ll get 3

For 5). Theyll be a downward force on the magnet cuz according to Newton’s 3rd law it’ll be opposite to the upward force on the wire

I don’t remember that one .. but it was so simple.. do u remember ur answer?

 

[Ahmed kooheji]

I found the oscillation question .. the one about finding the amplitude difficult

Yeah, that was pretty tough for me. Relatively though, this paper was on the easy side. Very straightforward.

How much do u think the threshold for A will be ?

this paper was def a little more trickier than last year, what do yall think? 60? for A?
