Answer 1

hey mate here is your answer

The Expression for Velocity of Body Moving in a Vertical Circle: Consider a small body of mass 'm' attached to one end of a string and whirled in a vertical circle of radius 'r'. In this case, the acceleration of the body increases as it goes down the vertical circle and decreases when goes up the vertical circle.
