Question

The electric field due to a uniformly charged non-conducting sphere of radius R as a function of the distance from its centre is resented graphically by

Options

A.
B.
C.
D.

Solution

       
Inside a uniformly charged non-conducting sphere, charge is uniformly distributed. So, field is there In such case electric field is directly proportional the distance from the centre. Outside the sphere field is inversely proportional to (distance)2. So,
