A student exerts a 2N for on a wall. What is the magnitude of the force the wall exerts on the student?

Fr = 2 [N]

Explanation:

To solve this problem we must use Newton's third law which tells us that the force applied on a body at rest is equal to the reaction force that acts in the opposite direction and with equal magnitude to the force applied.

Since the wall does not move when applying force, then it remains static (there is no movement)

We can use Newton's third law and say that the sum of the forces on the body is equal to zero. In this way, we propose the following equation.

∑F = 0

where:

F = force = 2 [N]

Fr = reation force [N]

Therefore.
