E)Q/2 $\pi$

Quizplus · Accepted Answer

The net electric flux through the inner surface of the shell is zero because of the Gauss's law. The electric flux passing through any closed surface is equal to the charge enclosed by the surface divided by the permittivity of free space. In this case, the inner surface of the shell encloses zero charge, therefore the net electric flux passing through it is zero.
