A stone tied with a string, is rotated in a vertical circle. The minimum speed with which the string has to be rotated

A

Is independent of the mass of the stone

B

Is independent of the length of the string

C

Decreases with increasing mass of the stone

D

Decreases with increasing in length of the string

Text Solution

Verified by Experts

The correct Answer is:
A
Since, `v("min") = sqrt(5gR)` [at lowest point]
It is independent of mass.
