Question

Using a horizontal force of 200 Newton, we intend to move a wooden cabinet across a floor at constant velocity. The friction force that will be exerted on the cabinet will be-


 A) equal to 200 N
 B) equal to -200 N
 C) equal to zero N
 D) equal to 400 N​

Answer 1

Answer:

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.
