A pulley in the form of a uniform circular disc of radius r and mass m lies on a smooth horizontal table surface as It is not hinged to the table. A massless inextensible string is wound around the pulley and goes over a massless smooth pulley P with a mass m1 hanging from its free end. If the hanging mass B is released from rest, find out the acceleration of the center C of the pulley.
