Question

A boy is whirling a stone tied with a string in a horizontal circular path as shown in the following

Answer 1

Answer:

When the boy is whirling a stone tied with a string in a circular path, the centripetal force acts towards the center of the circular path. However, when the string breaks the centripetal force ceases and there is no force acting. Thus, the stone as per Newtons first law will continue in a straight line and fly off along the tangent to the circular path.

Answer 2

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.
