A point charge $+Q$ is positioned at the centre of the base of a square pyramid as shown. The flux through one of the four identical upper faces of the pyramid is

A

$\frac{Q}{16\varepsilon_0 }$

B

$\frac{Q}{4\varepsilon_0 }$

C

$\frac{Q}{8\varepsilon_0 }$

D

None of these

Solution

Flux going in pyramid $=\frac{Q}{2 \varepsilon_{0}}$

Which is divided equally among all $4$ faces

$\therefore $ Flux through one face $=\frac{Q}{8 \varepsilon_{0}}$
