One end of a string of length 1.5 m is tied to a stone of mass 0.4 kg and the other end to a small pivot on a smooth vertical board. What is the minimum speed of the stone required at its lower most point so that the string does not slack at any point in its motion along the vertical circle ?

Assertion For looping a verticla loop of radius, r the minimum velocity at lowest point should be sqrt(5gr). Reason In this event the velocityh at the highest point will be zero.

A bob is attached to a string of length l whose other end is fixed and is given horizontal velocity at the lowest point of the circle so that the bob moves in a vertical plane. Match the velocity given at the lowest point of circle in column I with tension and velocity at the highest point of the circle corresponding to velocity of column I of column II
