A small sphere A of radius r and carrying a charge q is enclosed by a concentric spherical shell B of radius 2r carrying a charge 29. When A and B are connected by a conducting wire, the charge will flow from __________ to __________ .

Text Solution

Verified by Experts

A, B. Electric potential of inner sphere A is greater than that of outer spherical shell B and hence charge flows from A to B.
