A small disc of mass m is attached to one end of a light inextensible cord which passes through a frictionless hole in a frictionless horizontal tabletop At the other end of the cord is attached a weight of mass M Initially the disc is moving on a circle of radius R with an angular velocity If the hanging weight is pulled slightly downwards and then released it will undergo small amplitude oscillations Find the angular frequency of these oscillations
