#### Let    be the charge density distribution for a solid sphere of radius and total charge . For a point inside the sphere at distance from the centre of the sphere, the magnitude of electric field is Option 1) 0 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
