Water from a tap, maintained at a costant potential V, is allolwed to fall by drops of radius r through a small hole into a hollow conducting sphere of radius R standing on an insulating stand until it fills the entire sphere. Find the potential of the hollow conductor after it is completely filled with water.

Water from a tap maintained at a potential V is allowed to drop in drops of radius a through a small hole in to a hollow conducting sphere of radius R until it fill it. The potential of the sphere will be :

Acidified water from certain reservoir kept at a potential V falls in the form of small droplets each of radius r through a hole into a hollow conducting sphere of radius a. The sphere is insulated and is initially at zero potential. If the drops continue to fall untill the sphere is half full, the potential acquired by the sphere is
