A stone of mass m tied to string of length

l

is rotating along a circular path with constant speed v. The torque on the stone is

View answer and explanation

Correct option: D

Zero

Option D (Zero) is correct because the force is always radial, so the torque (

\vec{r} \times \vec{F}

) is zero.
