Question

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?​

Answer 1

Answer:

it will be 200N acc. to Newton's third law of motion

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.
