Question 4
A boy is whirling a stone tied with a string in a 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
(d) will move along a straight line perpendicular to the circular path away from the boy

Answer 1

(c) will move along a straight line tangential to the circular path
​​​​​​​
Once the centripetal force vanishes, the body moves with the tangential velocity at the moment of string break.
