Electric Flux & Gauss's Law

A charge Q $\mu$ C is placed at the centre of a cube, the flux coming out from each face will be

Show answer and solution

Answer: (a)

Each face gets $\dfrac{1}{6}$ of total flux $\dfrac{q}{\varepsilon_0}$ .
$q = Q \times 10^{-6}$ C, so $\phi_{face} = \dfrac{Q}{6\varepsilon_0} \times 10^{-6}$ .
So the answer is (a).
