Question
A boy is whirling a stone tied with a string in a horizontal circular path. If the string breaks, the stone
Options
will continue to move in the circular path
will move along a straight line towards the centre 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
Solution
will move along a straight line tangential to the circular path
Explanation:
If the string breaks, the force that was causing it to move along a circular path, i.e., centripetal force is no longer there, so the stone will move along a straight line tangential to the circular path.
