Question

A chair exerts a force of 20 N on a floor and is not moving. What force does

Answer 1

The floor exerts 20 N of force on the chair

Explanation:

We can answer this question by using Newton's third law, which states that:

"When an object A exerts a force (called action) on an object B, object B exerts an equal and opposite force (called reaction) on object A"

In this problem, we can identify:

- Object A as the chair

- Object B as the floor

This means that the force of 20 N exerted by the chair on the floor is the action, and so the force exerted by the floor on the chair is the reaction. Newton's third law states that these two forces are equal and opposite: therefore, the force exerted by the floor on the chair is also 20 N, but in the opposite direction.
