Q5.2Multiple choice
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.
