Q. In a cuboid of dimension $2 L \times 2 L \times L$ , a charge $q$ is placed at the center of the surface ' $S$ ' having area of $4 L^{2}$ . The flux through the opposite surface to ' $S$ ' is given by

$\frac{q}{12 ϵ _{0}}$

$\frac{q}{2 ϵ _{0}}$

$\frac{q}{3 ϵ _{0}}$

$\frac{q}{6 \in _{0}}$

Flux passing through shaded face $= \frac{q}{6 ε _{0}}$
