Solution

The correct option is D -120 N
The cabinet is moving with a constant velocity, i.e., the acceleration is zero. Therefore, the net force acting on the cabinet is also zero. It implies that the magnitude of the opposing frictional force is equal to the force exerted on the cabinet, i.e., 120 N. Thus, the frictional force is -120 N.
