A box is at rest on the floor. Which of the following force diagrams best represents the action-reaction pair of forces between the box and the floor?

Responses

A box with equal and opposing forces. A force vector (floor on box) points up, and an equal force vector (box on floor) points down.

The correct answer is: A box with equal and opposing forces. A force vector (floor on box) points up, and an equal force vector (box on floor) points down.

is that the first one

Yes! The first answer choice is the correct force diagram.

The correct answer is the first option: A box with equal and opposing forces. A force vector (floor on box) points up, and an equal force vector (box on floor) points down.
