Question
In the figure below, a solid sphere, of radius a = 1.10 cm is concentric with a spherical conducting shell of inner radius b = 2.00a and outer radius c = 2.40a. The sphere has a net charge q1 = +7.00 fC which is distributed uniformly through the sphere; the shell has a net charge of q2 = -q1. (a) What is the magnitude of the electric field at radial distance r = 0? (b) What is the magnitude of the electric field at radial distance r = a/4? (c) What is the magnitude of the electric field at radial distance r = a? (d) What is the magnitude of the electric field at radial distance r = 1.50a? (e) What is the magnitude of the electric field at radial distance r = 2.30a? (f) What is the magnitude of the electric field at radial distance r = 3.50a? (g) What is the net charge on the inner surface of the shell? (h) What is the net charge on the outer surface of the shell? [Need the answer for B overall.]Explanation / Answer
