1.	A mater scale is moving with unifrom velocity This implies .
Answer» the force acting on the SCALE is zero but a torque about the center of mass can act on the scale . the force acting on the scale is zero and the torque acting about CENTRE of mass of the scale is also zero . the total force acting on it need not be zero but the torque on it is zero . NEITHER the force nor the torque need to be zero. Solution :When a metre scale is moving with UNIFROM VELOCITY the force acting on the scale is zero and the torque acting about centre of mass of the scale is also zero .
