The electric field due to a uniformly charged spherical shell of radius R as a function of the distance from its center is represented graphically by:

The correct answer is Option (3)

Case 1: $r<R$

The electric field is zero because the net charge inside a Gaussian shell is -

$E=0$

Case 2: $r≥R$

The electric field is as if the entire charge is concentrated at the center -

$E=\frac{1}{4πε_0}\frac{Q}{r^2}$
