A long, hollow conducting cylinder is kept coaxially inside another long, hollow conducting cylinder of larger radius. Both the cylinders are initially electrically neutral.

A

A potential difference appears between the two cylinders when a charged density is given to the inner cylinder

B

A potential difference appears between the two cylinders when a charge density is given to the outer cylinder

C

No potential difference appears between the two cylinders when a uniform line charge is kept along the axis of the cylinders

D

No potential difference appears between the two cylinders when same charge density is given to both the cylinders

Text Solution

Verified by Experts

The correct Answer is:
A
There will be an electric field between two cylinders (using Gauss theorem). This electric field will produce a potential difference.
