Vedclass · Answer

We are given that a charge is placed at the centre of a square of side a at distance $a / 2$ :

Let us consider a cube that is enclosed and the square having a point charge at the centre.

A cube has six surfaces. Therefore flux is passing through six surface.

By using Gauss's law

$\Phi=\frac{ Qin ^{-}}{\epsilon_0} \quad\left\{ Q _{	ext {in }}= Q _{	ext {inclosed }}ight\}$

$Q _{ in }= q$

$\Phi=\frac{ q }{\epsilon_0}$

$\Phi$ is the flux electric flux passing through cube.

Step $2$: Electric flux through each side of the cube:

$\Phi=\frac{\Phi}{6}$

$\Phi=\frac{q}{6 \epsilon_0}$
