The frictional force exerted by the floor is equal in magnitude to F and acts in the direction opposite to motion. Net force is zero because the table moves with a constant velocity.
Using a horizontal force F, a table is moved across the floor at a constant velocity. How much is the frictional force exerted by the floor on the table?

Since the table moves across the floor at a constant velocity, its acceleration is zero. By Newton’s first law of motion, the net external horizontal force acting on the table must be zero. Therefore, the opposing frictional force exerted by the floor on the table must be exactly equal in magnitude to the applied horizontal force F, acting in the opposite direction.
