An electricity and magnetism problem by Vineet Kumar

Electricity and Magnetism Level 2

A ball of radius R is uniformly charged with the volume density p. The flux of the electric field strength vector across the ball's section formed by the plane located at a distance ( r < R) from the centre of the ball is given by : N ρ π r ( R 2 − r 2 ) / 9 Ɛ Nρπr(R^{2}-r^{2})/9Ɛ What is the value of N ?


The answer is 3.
