A non-uniformly charged sphere has charge density given by

\rho=\frac{a^2}{R}

where '

a

' is a constant. '

r

' is the distance from the centre and '

R

' is the radius of the sphere. Then the total charge inside the sphere is proportional to

View answer and explanation

Correct option: D

{R}^4

Option D (

{R}^4

) is correct because the total charge inside the sphere is proportional to

{R}^4

after integrating the charge density over the volume of the sphere.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase
