1000 similar electrified rain drops merge together into one drop so that their total charge remains uncharged. How is the electric energy affected ?

One thousand similar electrified raindrops merge into one so that their total charge remains unchanged Find the change in the total electric energy of the drops, assuming that the drops are spherical and that small drops are at large distance from one another [Energy increase by 100 times]

One thousand similar electrified raindrops merge into a single one so that their total charge remains unchanged. Find the change in the total electrostatic energy of the drops, assuming that all the drops are spherical and the small drops were initially at large distances from one another.

The electric field required to keep a water drop of mass 'm' just to remain suspended in air, when charged with one electron, is

1000 small drops of water each of radius 'r' are joined together to form a single drop of water During the process the change in energy has raised the temerature . If T is the surface tension of the water , d is density , the rise in temperature is

125 rain drops are combined to from a single drop . The ratio of the total energy of 125 drops to that of a single drop is

1000 small water drops each of radius r and charge q coalesce together to form one spherical drop. The potential of the bigger drop is larger than that of the smaller one by a factor
