Using a horizontal force of 200 N. we Intend to move a wooden cabinet across a floor at a constant velocity. What is the friction force that will be exerted on the cabinet?

Text Solution

Verified by Experts

The cabinet will move with a constant velocity, if the net force acting on it is zero. So, the force of friction on the cabinet is 200 N in a direction opposite to the direction of motion of the cabinet.
