The electric field due to uniformly charged sphere of radius `R` as a function of the distance from its centre is represented graphically by

Options

A.
B.
C.
D.

Answer

B

Explanation

The magnitude of the electric field at a point exterior to the sphere is `(1)/(4piepsi_(0)r^(2))` the magnitude of electric field inside the sphere is given by `(1)/(4piepsi_(0))(Qr)/(a^(3))` The field is directly proportional to r.
