Question

action and reaction forces
a student is high - fiving a friend. if the student exerts a 5 n leftward force on their friends hand, what reaction force will their friends hand exert on their hand?
5 n to the right
5 n upward
5 n downward
5 n to the left

Explanation:

According to Newton's Third Law of Motion, action and reaction forces are equal in magnitude and opposite in direction. The student exerts a 5 N leftward force (action force), so the reaction force from the friend's hand should be equal in magnitude (5 N) and opposite in direction (rightward).

Answer:

A. 5 N to the right
