A disc of mass 2 kg and radius 0.2 m is rotating about an axis passing through its centre and perpendicular to its plane with an angular velocity 50 rad/s . Another disc of mass 4 kg and radius 0.1m rotates about an axis passing through its centre and perpendicular to its plane with angular velocity 100 rad/s. If the two disc are coaxially coupled, then the angular velocity of coupled system would be

A closed tube, partly filled with a liqyid and set horizontal, is rotated about a vertical axis passing through its centre. IN the process, the moment of inertia of the system about its axis would
