Question

using a horizontal force of 200 Newton 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

Answer 1

as according to Newton's third law of motion

action is always equal to the reaction we are moving the wodden cabinet forward that the reaction is occurred in the opposite direction
so frictional force will be also 200 Newton

Answer 2

Answer:

Since the wooden cabinet is to be moved at constant velocity, this means that the whole force of 200 N will be used to overcome the force of friction. Thus, the force of friction exerted on the cabinet will be equal to the force applied, which is 200 N.
