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 charge $2 πxdxσ is V 2 πxdxσ put the value of V and integrate inform for any problem$

A small metal ball is being pulled gradually on a fixed frictionless hemisphere as shown in the figure. Radii of the ball and that of the pulley are much smaller than that of the hemisphere. As the ball slides from the bottom to a position close to the top of the hemisphere, how do the magnitudes of pulling force F and contact force R between the ball and the hemisphere change?

(a) F increases and R decreases.

(b) F decreases and R increases.

(c) F decreases and R remains unchanged.

(d) F remains unchanged and R decreases.
