-
Force is directly proportional to the acceleration and mass of an object. (This is based on Newton's second law of motion, \( F = ma \), where \( F \) is the force, \( m \) is the mass, and \( a \) is the acceleration.)
-
The box exerts 10 N of force downward. (Since the two ropes are exerting a total upward force of 10 N, the box must exert an equal and opposite force downward to remain stationary, according to Newton's third law of motion.)
