A long, hollow conducting cylinder is kept coaxially inside another long, hollow conducting cylinder of larger radius. Both the cylinder 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

A conducting liquid bubble of radius $$a$$ and thickness $$t(t < < a)$$ is charged to potential V. If the bubble collapses to a droplet, find the potential on the droplet.

$$V{\left[ {{2a \over {3t}}} \right]^{1/3}}$$

$$V{\left[ {{7a \over {3t}}} \right]^{1/3}}$$

$$V{\left[ {{a \over {3t}}} \right]^{1/3}}$$

$$V{\left[ {{5a \over {9t}}} \right]^{1/3}}$$
