An isolated conducting spherical shell of radius 30 cm is given a positive charge such that the maximum intensity of the electric field at its surface is 1.8 × 106 NC-1. An equal amount of negative charge is given to another isolated conducting spherical shell of radius 60 cm. If the first shell is now placed concentrically inside the second shell, find the total electrostatic energy stored in the system.
