Regarding Q2, e and f -> The energy is 1/2*Q^2*C. We have Q at this oment of time and C comes out from the geometry of the capacitor. Now, guess what - it's wrong. Any ideas?

sorry i meant Q3, d and e

it does not work for me also

25.5

C is wrong ...

Hey boss, how did u come across this topic if you have not googled the question? It's obvious that you cheat also! BTW - for C just use the value for b (the one in the question) b=(di/dt)

come on, anyone?

1/2 m vf^2=1/2 m vi^2+GMm/r - it's correct!

and c

it's the first one - 9.34
