Question

A boy is whirling a stone tied with a string in an horizontal circular path. If the string breaks, the stone : *

will continue to move in circular path

will move along a straight line towards the center of the circular path

will move along a straight line tangential to the circular path

will move along a straight line perpendicular to the circular path away from the boy

​

Answer 1

Ans: 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.
