A soap bubble is charged to a potential 12 V. If its radius is dubled, then the potential of the bubble becomes

A soap bubble of radius R = 3 cm and thickness t = 10^(-2) mm is charged to a potential of V = 0.3 volt. The bubble burst and falls as a spherical drop. Determine the potential of the drop

A soap bubble is charged to a potential of 16V. Its radius is then doubled. The potential of the bubble now will be

There are 27 drops of a conducting fluid. Each drop has radius r , and each of them is charged to the same potential V_1 . They are then combined to from a bigger drop. The potential of the bigger drop is V_2 . Find the ratio V_2//V_1 . Ignore the change in density of the fluid on combining the drops.

Metallic sphere of radius R is charged to potential V. Then charge q is proportional to

There are 27 drops of a conducting fluid. Each has a radius r and they are charged to a potential V_(0) . They are then combined to form a bigger drop. Find its potential.

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
