Question

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) the 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
