Calculate potential energy of a point charge - q placed along the axis due to a charge + Q uniformly distributed along a ring of radius-, R. Sketch P .F. as a function or axial distance z from the centre of the ring. Looking at graph, can you see what would happen if - q is displaced slightly from the centre of the ring (along the axis) ?

Skecth P.E. as a function of a axial distance z from the center of the ring, Looking at graph, can you see what happen if -q is displaced slighlty from the centre of the ring (along the axis) ?

In a free space, a thin rod carrying uniformly distributed negative charge -q is placed symmetrically along the axis of a tin ring of radius R varrying uniformly dostributed charge Q. The mass of the rod is m and length is l=2R . The ring is fixed and the rod is free to move. The rod is displaced slightly along the axis of the ring and then released. Find the period T to the small amplitude oscillations of the rod.
