Quizplus · Accepted Answer

The electric flux through a closed surface is given by Gauss's law as $\Phi = \frac{q}{\epsilon_0}$, where $q$ is the total charge enclosed by the surface and $\epsilon_0$ is the permittivity of free space. This equation shows that the electric flux depends only on the amount of charge enclosed by the surface and not on the size or shape of the surface. Therefore, doubling the radius of the spherical surface does not change the net electrical flux through it.
