Solution

Step 1: Given:

Stone mass = m

string of length = l

velocity = V

Step 2: Formula

Torque is given byτ=r×F=r×mv2r

a is acceleration.

r is the axle radius.

v is the speed.

m is the mass of stone.

Step 3: Solution

As the direction of centripetal force and position vector is directed toward center

T=r×F=rFsinθhereθ=0oThereforeT=0

The torque will be zero.
