A student wants to investigate uniform circular motion for an object in an amusement park ride. The student will ride inside of a hollow cylindrical tube that pins the student to the inside wall of the tube as it spins. As the tube spins, the bottom of tube is removed such that the tube becomes open at the top and bottom. At the instant shown in figure 1, the student is pinned against the right side of the tube. A diagram showing the forces exerted on the student is shown in figure 2. When the ride is finished, the student safely falls onto the padded cushions below the floor of the tube. Which of the following represents the magnitude of the force that the student exerts on the right side of the tube?

a). F_Friction, because the student is in direct contact with the tube. 

b). F_Normal, because the force that the student exerts on the right side of the tube is an action-reaction pair with the normal force that the tube exerts on the student. 

c). F_Gravity, because Earth's gravitational field is continually trying to pull the student down to Earth's surface.

d). The vector sum of F Friction and F Normal because both forces are the result of the student being in direct contact with the right side of the tube and not sliding down.
