A rider of mass \(m\) sits on a bench inside a compartment of an amusement park ride that travels in a vertical circle of radius \(R\). The ride operates at various constant angular speeds \(\omega\). Which of the following graphs best represents the magnitude of the normal force \(F_N\) exerted by the bench on the rider when the compartment is at the lowest point of the circular path as a function of \(\omega\)?
