A conducting bolloon of the radius a is charged to potential V_(0) and held at a large height above the earth ensures that charge distribution on the surface of the balloon remains unaffected by the presence of the earth. It is connected to the earth through a resistance R and a value in the balloon is opened . The gas inside the balloon escapes from value and the size of the balloon decreases. The rate of decrease in radius of the balloon is controlled in such a manner that potential of the balloon remains constant. Assume the electric permittivity of the surrounding air equals to that of free space (epsilon_(0)) and charge cannot leak to the surrounding air. The rate at which radius r of the balloon changes with time is best represented by the equation
