What's the electric field with a point charge not in the center of the sphere?
 
That's a hollow conducting sphere link img: http://i.stack.imgur.com/dXzo8.png

My charge is at P (10uC). R = 0.15m. PS = 0.05m. DS = 0.35m. What's the electric field at point D?

I think the coulomb's law formula works straight away for this
E = kq/r(^2) where k = 9*10(^9), q = 10*10(^-6), r = DS - PS = 0.30
The ans will be 10(^5)
