Question

a point particle is held on the axis of a ring of mass m and radius
'r' at a distance r from its center 'c' WHEN RELEASED IT REACHES '
c' under the gravitational attraction of the ring What will be its
speed at 'c' ?

On the particle centripetal force of attraction acts so the particle execute S
 H  M
Therefore the velocity at the centre of the ring is;             v=ωrwhere r is the angular frequency of the oscillatory motion
