A coaxial transmission line consists of two concentric cylinders.The inner cylinder has radius r1 and the outer cylinder has radius r2. The inner cylinder has a surfacecharge density ρS C.m-2, that is uniformly distributed along its length. The outer cylinder has the same totalcharge as the inner cylinder, distributed over its inner surface but is of opposite polarity. Determine theelectric field amplitude,
a) inside the inner cylinder [r < r1]
b) between the cylinders [ r1 < r < r2]
c) outside the outer cylinder [r > r2]
