Answer to Problem 1CQ
The force that is not exerted on the bathroom scale is the weight of the scale.
Explanation of Solution
The weight of the body is the force exerted on a particle or object by acceleration due to gravity. The force applied to a body by another body that is in contact with it is called contact force. The normal force is the component of contact force that is perpendicular to the surface that an object in contact.
The contact force due to the floor and contact force due to the person’s feet are the normal forces acting on the scale in the upward direction. The weight of the person is the downward force acting on the scale. The weight of the scale is the normal force exerted on the floor by the scale. As a result, the weight of the scale is not a force exerted on the scale.
Conclusion:
Therefore, the force that is not exerted on the bathroom scale is the weight of the scale.
