A metre scale is moving with uniform velocity. This implies .

A

the force acting on the scale is zero, but a torque about the centre of mass can act on the scale.

B

he force acting on the scale is zero and the torque acting about centre of mass of the scale is also zero.

C

the total force acting on it need not be zero but the torque on it is zero.

D

neither the force nor the torque need to be zero.

Text Solution

Verified by Experts

The correct Answer is:
B
When a metre scale is moving with uniform velocity, the force acting on the scale is zero and the torque acting about centre of mass of the scale is also zero.
