PhysicsSystems of Particles and Rotational MotionMHT CET

A solid sphere of mass 'M' and radius 'R' is rotating about its diameter. A disc of same mass and radius is also rotating about an axis passing through its centre and perpendicular to the plane but angular speed is twice that of the sphere. The ratio of kinetic energy of disc to that of sphere is [MHT-CET 2021, MHT-CET 2021]
