The electric charges are distributed in a small volume. The flux of the electric field through a spherical surface of radius

10\mathrm{ }\;cm

surrounding the total charge is

20\mathrm{ }\;Vm.

The flux over a concentric sphere of radius

20\;\mathrm{ }cm

will be

View answer and explanation

Correct option: A

20\mathrm{ }\;Vm.

Option A is correct. According to Gauss's law, the electric flux through a closed surface depends only on the enclosed charge, not the radius of the sphere.
