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

Question

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 potential difference appears between the two cylinders when a charge density is given to the inner cylinder, a potential difference appears between the two cylinders when a charge density is given to the outer cylinder, no potential difference appears between the two cylinders when a uniform line charge is kept along the axis of the cylinders, no potential difference appears between the two cylinders when same charge density is given to both the cylinders

MARKS App · Accepted Answer

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