Homework Statement
Consider a conductor in the shape of a hollow sphere with inner radius A and outer radius B. The sphere has a net positive charge +q.
A negative point charge of value -2q is placed at the center of the sphere (r=0). Determine the electric field in the three regions of space:
i) r < A
ii) A < r < B
iii) r > B
The Attempt at a Solution
Since this is a conductor, I thought part (i) and (ii) both have 0 Electric Field because the charge on the inside of the sphere will move to the surface, since this is a conductor.
But this is wrong. I need some help here.
