A ring of radius R having a uniformly distributed charge Q is fixed in a horizontal plane A bead of mass m and an unknown charge stays in equilibrium at such point on the vertical axis of the ring that if it is displaced slightly up or down it undergoes oscillatory motion Find charge on the bead Intensity of gravitational field is g Bead R
