One end of a spring of negligible unstretched length and spring constant k is fixed at the origin 0 0 A point particle of mass m carrying a positive charge q is attached at its other end The entire system is kept on a smooth horizontal surface When a point dipole p pointing towards the charge q is fixed at the origin the spring gets stretched to a length and attains a new equilibrium position see figure below If the point mass is now displaced slightly by from its equilibrium position and released it is found to oscillate at frequency Ik m The value of is
