Friction Force Calculation
Friction force is the force that opposes the motion of an object when it is in contact with a surface. In this case, we are trying to move a wooden cabinet across a floor at a constant velocity with a horizontal force of 200 N.

Force of Friction
The friction force can be calculated using the formula:
Friction force = Force applied - Force of friction

Calculating the Friction Force
Given that the horizontal force applied is 200 N and the cabinet is moving at a constant velocity, the friction force must be equal and opposite to the applied force to keep the cabinet moving at a constant velocity. Therefore, the friction force exerted on the cabinet is 200 N.

Explanation
When an object is moving at a constant velocity, the forces acting on it are balanced. In this case, the force of friction is equal in magnitude but opposite in direction to the applied force. This ensures that the cabinet does not accelerate or decelerate while moving across the floor.
Therefore, the friction force exerted on the wooden cabinet as it is being moved across the floor at a constant velocity with a horizontal force of 200 N is also 200 N.
