Electric Flux & Gauss's Law

A charge Q is situated at the corner of a cube, the electric flux passed through all the six faces of the cube is

Show answer and solution

Answer: (b)

A corner charge is shared equally by 8 cubes meeting at that corner.
Flux through this cube $= \dfrac{Q}{8\varepsilon_0}$ .
So the answer is (b).
