Which of the following statements correctly represents Newton's third law and the interaction between the child and desk? The desk exerted slightly more than 15 N of force on the child, but the force is directed to the left. The desk exerted slightly less than 15 N of force on the child, but the force is directed to the left. The desk exerted exactly 15 N of force on the child, but the force is directed to the left. The desk did not exert any force on the child. Novt
