Question

A system consists of a ball of radius R carrying a spherically symmetric charge and the surrounding space filled with a
charge of volume density p=alr, where a is a constant, P is the distance from the centre of the ball. Find the ball's charge
for which the magnitude of the electric field strength vector is independent of r outside the ball. How large is this strength?
The primitivities of the ball and the surrounding space are assumed to be equal to unity.​
