using the 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?

the frictional force will be 200N in the opposite direction
this can be justified as follows
as the block is moving with constant velocity, there is no acceleration. Which means that net force acting on it is zero.
for net force to be zero, both the forces ( i.e the applied force and frictional force) must be equal and opposite.
So, we get frictional force as 200N in the opposite direction.

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.
