Question

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

• A. a potential difference appears between the two cylinders when a charge density is given to the inner cylinder.
• B. a potential difference appears between 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 cylinders.

Hint:

In conductors, a potential difference exists only if there is an electric field between them.

Answer 1

The Correct Option is A
