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:

Since, a horizontal force of 200N is used to move a wooden cabinet, thus a friction force of 200N will be exerted on the cabinet. Because according to third law of motion, an equal magnitude of force will be applied in the opposite direction.

Explanation:

Total force on body=0

force+friction=total force on body

200+friction=0

friction=-200N

Answer 2

Explanation:

since, a horizontal force of 200N is used to move a wooden cabinet, thus a friction force of 200N will be exerted on the cabinet. Because according to third law of motion, an equal magnitude of force will be applied in the opposite direction.
