Question

A charge q is located at the centre of a cube . The electronic flux through any face is

Answer 1

According to Gauss's Law,

............................(1)

Cube has six equal faces, so electric flux pass through each would be equal.

If A = area of face

and E = field intensity.

Then total flux = 6(E*A) = q/ε

So, net electric flux passing through each face of the cube is given by

E*A = q/6ε
