Expert Answer
The torque acting on the centre of gravity will be
Now, the distance of centre of mass with itself will be zero.
Therefore, the torque due to mg on a body is zero. However, the torque on other points on the body will not be zero.
Hence, we can say that the centre of gravity cancels all the torques due to weight (mg) on a body.
