In this why do we have to take the torque of Mw 2R A disc shaped body having a hole as shown in the figure of mass m 10 kg and radius R 10 m is performing pure rolling motion 9 on a rough horizontal surface In the figure point O is geometrical center of the disc and at this instant the centre of mass C of the disc is at same horizontal level with O The radius of gyration of the disc about an axis passing through C and perpendicular to the plane of the disc is R and at the instant shown the angular velocity 2 of the disc is c g rad sec in clockwise sense g is gravitation VR acceleration 10 m s Find angular acceleration in rad s of the disc at this instant C R 2
