A conducting balloon of the radius a is charged to potential

Last updated: 6/7/2023

A conducting balloon of the radius a is charged to potential V 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 valve in the balloon is opened The gas inside the balloon escapes from valve 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 free space 0 and charge cannot leak to the surrounding air hor massume the electric permittivity of the surrounding air equals to that of mo ang matho
