Question

A stone of mass $m$ tied to a string of length $l$ is rotated in a circle with the other end of the string as the centre. The speed of the stone is $\upsilon$ . If the string breaks, the stone will:

• A. move towards the centre
• B. move away from the centre
• C. move along tangent
• D. stop

Answer 1

Answer: (C)

move along tangent

Answer 2

When the string breaks, centripetal force on stone becomes zero. So, net acceleration on the stone is zero. So, stone move on straight path i.e., along tangent.
