A charge $q$ is located at the centre of a cube. The electric flux through any face is

Question

Professor PC Thomas Classes · Answer

The total flux through the cube $\phi_{	ext {total }}=\frac{q}{\varepsilon_{0}}$
$	herefore \quad$ The electric flux through any face
$$
\phi_{	ext {face }}=\frac{q}{6 \varepsilon_{0}}=\frac{4 \pi q}{6\left(4 \pi \varepsilon_{0}ight)} .
