Using a horizontal force ` 200N`, we intend to move a wooden cabinet across a floor at constant velocity. What is the frictional force that will be exerted on the cabinet?

Text Solution

Verified by Experts

The correct Answer is:

200 N

The cabinet will move with constant velocity only when the net force on it is zero . Therefore , force of friction on the cabinet =200 N, in a direction opposite to the direction of motion of the cabinet.
