Question

A particle of mass $m$ is released from rest from point $P$ at $x=x_0$ on X-axis from origin $O$, and falls vertically along y-axis as shown in Fig. What is the magnitude of the torque acting on the particle at time $t$, when it is at the point $Q$ w.r.t. $O$?

• A. $m{x}_o$
• B. $mg{x}_o^2$
• C. 2mg
• D. $mg{x}_o$

Answer 1

The correct option is D $mg{x}_o$
