A charge -Q is fixed at point P. A dipole with dipole moment P is placed at’the center of base and perpendicular to its plane as shown in Fig. 3.122. Find a). the force on dipole due to charge particles, and b). the potential energy of the system.

a charge q is imparted to the inner shells. Now B C find the potential difference between the shells. Note that finally key K2 remains closed. Four charge the particles each having charge Q are fixed at the comers of the base (at A key K1 is closed and opened and then key K2 is closed and opened. After the keys K1andK2 are alterbately closed n times each Two concentric shells of radii R and 2R are shown in (Fig. 3.115). Initially
