A spherically symmetric charge distribution is characterized by a charge density having the following variation :rho (r ) = rho_0 (1 - r/R) for r lt R rho (r ) = 0for r ge R. Where r is the distance from the centre of the charge distribution and rho_0 is a constant. The electric field at an internal point (r lt R) is |
