Figure 1 Fscale FGravity Figure 2

A student is riding a Ferris wheel that moves at a constant tangential speed around a vertical circular path of radius R, as shown in Figure 1. The student is sitting on a scale. At the instant the moving student is located at point P, the scale exerts a force of magnitude Fscale on the student and Earth exerts a force of magnitude FGravity on the student, as shown in the free-body diagram in Figure 2. Which of the following statements provides reasoning that supports and correctly identifies the magnitude of the force that the student exerts on the scale when the student is at point P ? ( A ) FScale, because that is the magnitude of the force exerted by the scale on the student. B) FScale, because that is the magnitude of the only upward force exerted on the student. ☺ ) FGravity, because Earth exerts a gravitational force on the scale. @ FGravity, because the magnitude of the force exerted on a scale must equal the weight of the person on the scale.
