A small bead of mass m is constrained to slide without friction inside a circular vertical hoop of radius r which rotates about a vertical axis at a frequency of f.
a) Find the angle where the bead will be in equilibrium--that is, where it will have no tendency to move up or down along the hoop.
b) If f = 2.00rev/s and r =22.0cm, determine what is the angle?
