#### What is the flux through a cube of side 'a' if a point charge of 'q' is at one of its corner? Option 1) Option 2) Option 3) Option 4)

As we learnt in

Gauss's Law -

Total flux linked with a closed surface called Gaussian surface.

Formula:

- wherein

No need to be a real physical surface.

Qenc - charge enclosed by closed surface.

Eight identical cubes are required so that the given charge q appears at the centre of the bigger cube.
