Problem 3 Chapter 21 from Pandey

A particle of mass m and charge –Q is constrained to move along the axis of a ring of radius a. The ring carries a uniform charge density +λ along its length. Initially the particle is in the center of the ring where the force on it is zero. Show that the period of oscillation of the particle when it is displaced slightly from its equilibrium position is given by .
