Disc of mass M=10 kg and radius R=50 cm is revolving about fixed vertical axis on smooth horizontal surface with angular velocity `omega_(0)=10 rad//s`. A block of mass m=5kg is connected throgh disc through slack string as shown in the diagram. Find the angular velocity (in rad/s) when string becomes taut.

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
