A spherical rubber balloon carries a total charge Q distributed uniformly over its surface. At t = 0, the radius of the balloon is R. The balloon is then slowly inflated until its radius reaches 2R at the time t,. Determine the electric field due to this charge as a function of time a) at the surface of the balloon, b) at distance R from the center of the balloon, and c) at distance 2R from the center of the balloon.
