Question

magnitude and direction of force quick check
two ropes are being used to suspend a box. each rope is exerting 5 n of upward force. if the forces are balanced and the box is stationary, how much force is being exerted by the box itself and in which direction? (1 point)
○ the box exerts 10 n of force downward.
○ the box exerts 5 n of force downward.
○ the box exerts 10 n of force upward.
○ no forces are being exerted by the box.

Explanation:

To solve this, we use the concept of balanced forces (Newton's laws). The upward forces from the ropes must balance the downward force from the box (weight, due to gravity). Each rope exerts 5 N upward, so total upward force is \(5\,\text{N} + 5\,\text{N} = 10\,\text{N}\). For forces to be balanced (box stationary), the downward force from the box must equal the total upward force. Thus, the box exerts 10 N downward.

Answer:

The box exerts 10 N of force downward.
