In Figure a solid sphere of radius a = 2.00 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 uniform charge q1 = + 5.00fC; the shell has a net charge q2 = q1. What is the magnitude of the electric field at radial distances?

(a) r = 0,

(b) r = a/2.00,

(c) r = a

(d) r = 1.50a,

(e) r = 2.30a, and

(f) r = 3.50a? What is the net charge on the

(g) Inner and

(h) Outer surface of theshell?
