Question
In Figure 23-50, a solid sphere of radius a = 4.00 cmis concentric with a spherical conducting shell of inner radiusb = 2.00a and outer radius c =2.40a. The sphere has a net uniform chargeq1 = +6.11 fC; the shell has a net chargeq2 = –q1. What is themagnitude (in N/C) of the electric field at radial distances(a)r = 0 cm,(b)r = a/2.00,(c)r = a,(d)r = 1.50a,(e)r = 2.30a, and(f)r = 3.50a? What is the netcharge (in C) on the (g) inner and(h) outer surface of the shell?
