A long charged cylinder of linear charged density `lambda` is surrounded by a hollow co-axial conducting cylinder. What is the electric field in the space between the two cylinders?

Text Solution

Verified by Experts

`lambda(2 pi epsilon_(0)r)` where r is the distance of the point from the common axis of the cylinders. The field is radial, perpendicular to the axis.
