small ring is threaded on an inextensible frictionless cord of length 2l.
The ends of the cord are fixed to a horizontal ceiling. In equilibrium, the
ring is at a depth h below the ceiling. Now the ring is pulled aside by a
small distance in the vertical plane containing the cord and released.
Find period of small oscillations of the ring. Acceleration of free fall is g.

Let potential of a disc of radius x is V. For this, see video given below
Now potential energy of this disc with a circular layer of charge2πxdxσ is V2πxdxσput the value of V and integrateinform for any problem
