Q.No.12.7: - Is E necessarily zero inside a charged rubber balloon if balloon is spherical? Assume that charge is distributed uniformly over the surface.

Q.No.12.7: - Is E necessarily zero inside a charged rubber balloon if balloon is spherical? Assume that charge is distributed uniformly over the surface.

Ans: - According to Gauss’s Law if the charge enclosed in the closed surface is zero then flux will be zero out of that surface. In this case the charge is distributed uniformly over the surface and no charge is present

Hence electric field intensity will be zero inside a spherical balloon which has uniformly distributed charge on its surface.
