Unformatted text preview: 8. Shown in the ﬁgure below are two concentric CONDUCTING spheres
of charge. Because the spheres are conducting, the charge will not be
uniformly distributed over their volumes, but will instead accumulate on
the surfaces. The inner sphere has a total charge -Q and the outser sphere
has a total charge +2Q. Use Gauss Law to determine all the following: b
a I II III c IV
(a) The electric ﬁeld in Region I (r > c).
(b) The electric ﬁeld in Region II (b < r < c).
(c) The electric ﬁeld in Region III (a < r < b).
(d) The electric ﬁeld in Region IV (r < a).
(e) The charge on the surface r=c.
(f) The charge on the surface r=b.
(g) The charge on the surface r=a. 8 ...
