Unformatted text preview: 7. Shown in the ﬁgure below are two concentric cylinders of charge. The
cylinders are uniformly ﬁlled with charge densities ±ρ Coulombs as indim3
cated in the ﬁgure. The space between the cylinders, a < r < b, is empty.
Use Gauss Law to ﬁnd the electric ﬁeld in each of these regions: b
a I II III c IV
−ρ +ρ (a) Region I (r > c).
(b) Region II (b < r < c).
(c) Region III (a < r < b).
(d) Region IV (r < a). 7 ...
