### When is electric flux zero? [closed]

While studying about electric flux, I came across a problem which asked to calculate net electric flux through uncharged closed hemisphere. The answer was 0. But electric flux is amount of field line ...
For a conducting sphere of radius $a$ and charge $Q$ surrounded by a concentric spherical shell of radius $b$ and charge $-Q$ (where $b > a$), I am aware that the electric field in the volume ...
