the centre; a, b are constants.
Then the charge density inside ball is​

Answer 1

Answer:

The electrostatic potential inside a charged spherical ball is given by ϕ=ar2+b where r is the distance fromthe centre : a,b are constants. Then the charge density inside the ball is.

Explanation:

When a conductor is at equilibrium, the electric field inside it is constrained to be zero. Since the electric field is equal to the rate of change of potential, this implies that the voltage inside a conductor at equilibrium is constrained to be constant at the value it reaches at the surface of the conductor.
