A positive charge is at the centre of a spherical balloon of radius 5m, situated in air. The electric potential on the surface of the balloon is 2 kV (kilo-volt). The balloon is then inflated so that its radius becomes 10 m, with the charge still at the centre of the balloon. Assume that the relative permittivity of air, e,-1. What is the electric potential at the surface of the ballon after it has been inflated? Ans. 1 kV. Enter the correct answer below. Character Please enter a number for this text box. Limit 5
