The electrostatic potential inside a charged spherical ball is given by `phi=ar^2+b` where r is the distance from the centre and a, b are constants. Then the charge density inside the ball is:

The electrostatic potential inside a charged spherical ball is given by phi = ar^(2) + b , where r is distance from the center of the ball, a and b are constants. Calculate the charge density inside the ball.

The electric potential in a region is given as V = -4 ar^2 + 3b , where r is distance from the origin, a and b are constants. If the volume charge density in the region is given by rho = n a epsilon_(0) , then what is the value of n?

The potential inside a charged ball depends only on the distance r of the point form its centre according to the following relation V=Ar^(2)+B volts The charge density inside the ball will be

A non-conducting spherical ball of radius R contains a spherically symmetric charge with volume charge density rho=kr^(2) where r is the distance form the centre of the ball and n is a constant what should be n such that the electric field inside the ball is directly proportional to square of distance from the centre?
