Unformatted text preview: 6. Shown in the ﬁgure below are two concentric spheres of charge. A charge
+Q is uniformly distributed over the outer sphere between r=b and r=c.
A charge -Q is uniformly distributed over the inner sphere r < a. The
space between the spheres, a < r < b, is empty. Use Gauss Law to ﬁnd b

the electric ﬁeld in each of these regions:
(a) Region I (r > c).

(c) Region III (a < r < b).
(d) Region IV (r < a). 6 c ...
