Quizplus · Accepted Answer

Both people are experiencing the same gravitational force due to their mass, and this force is transmitted through the elevator in equal magnitude and opposite directions. Therefore, the force the floor exerts on the first person and the force the rope exerts on the second person are equal and have the same direction.
