A charge is initially surrounded by a cubic Gaussian surface whose volume is d³. The cubic surface is replaced by a spherical surface of radius d/2. The net flux of the spherical surface is

Question

Quizplus · Accepted Answer

The net electric flux through a closed surface is given by Gauss's Law, which depends only on the charge enclosed by the surface, not on the shape or size of the surface. Therefore, replacing a cubic surface with a spherical one, while keeping the charge enclosed the same, does not change the net flux.
