Question

action and reaction forces
15 n
a box is sitting on a table.
if the box exerts a 15 n
downward force on the table,
what reaction force will the
table exert on the box?
15 n to the left
15 n to the right
15 n downward
15 n upward

Explanation:

Step1: Recall Newton's Third Law

Newton's third law states that for every action, there is an equal and opposite reaction. The action force here is the box exerting a 15 N downward force on the table.

Step2: Determine the Reaction Force

The reaction force should be equal in magnitude (15 N) and opposite in direction (upward) to the action force. So the table will exert a 15 N upward force on the box.

Answer:

15 N upward
