A particle like ball is connected to one end of a light inextensible cord, other end of which is connected to a very thin frictionless fixed vertical rod. The entire length of the cord is wound around the rod into a large number of closely spaced turns and the ball is held touching the rod. When the ball is released, the cord gradually unwinds and the ball startscircling the rod. What angle does the cord make while it is unwinding the rod
