A boy is whirling a stone tied with a string in an horizontal circular path. If the string breaks, the stone
(a) will continue to move in the circular path
(b) will move along a straight line towards the centre of the circular path
(c) 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

Question

A boy is whirling a stone tied with a string in an horizontal circular path. If the string breaks, the stone
(a)	will continue to move in the circular path
(b)	will move along a straight line towards the centre of the circular path
(c)	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

Accepted Answer

Soln:

Answer is (c) will move along a straight line tangential to the circular path
Explanation:
At any instance of time object in circular motion tend to be in rectilinear motion. Object keeps on moving due to centripetal force and it moves along a straight line tangential to the circular path when strings breaks.
