Question

State whether true or false.
A stone is tied to a string and is whirled in a horizontal circle. If the string breakes when the tension in it becomes greater that $T$, then the maximun centripetal force that can act on the stone is $2T$.

• A. True
• B. False

Answer 1

The correct option is B False

The tension in the string is the cause of the centripetal force acting on the stone, to keep it in a circular motion. Hence, tension in the string has to be equal to the centripetal force in any case. Therefore, the maximum centripetal force that can act on the stone is equal to the maximum tension the string can handle.

Hence, the given statement is false
