Which example best represents balanced forces?

The correct answer is "an elevator stopped on the third floor".

Explanation:

Balanced forces are those in which forces of action and reaction are produced on a body, canceling each other out and preventing this body from changing its speed. In this way, we can say that the acceleration experienced by that body is zero. In this way, an elevator stopped on the third floor has a force exerted by the weight and another by the tension of the cable that is balanced.

Have a nice day!
