A

The forces may be acting radially from a point on the axis

B

The forces may be acting on the axis of rotation

C

The forces may be acting parallel to the axis of rotation

D

The torque caused by some forces may be equal and opposite to that caused by other forces

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
For all the options, net external torque on a system of particles can be zero. So, allare compatible with it.
