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

Options

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 the cylinders.
