Answer :
Final answer:
The magnitude of the normal force acting on the wooden box is 195 N.
Explanation:
According to Newton's third law of motion, the normal force is equal in magnitude and opposite in direction to the force exerted by an object on a surface. Since the wooden box is being pulled to the right with a 195 N force at a constant velocity, the magnitude of the normal force acting on the box is also 195 N, but in the opposite direction.
