Question

a girl is wearing a stone tied with a string which force keeps the stone to move in circular motion​

Answer 1

Answer:

In circular motion, the direction of velocity at a point is always along the tangent at that point. If string breaks, then the centripetal force acting on the stone becomes zero and it will move along a straight line tangential to the circular path.

Answer 2

Explanation:

When the girl is whirling a stone tied with a string in a circular path, the centripetal force acts towards the center of the circular path.
