A uniform disc of mass M and radius R is rotating in a horizontal plane about an axis perpendicular to its plane with an angular velocity `omega`. Another disc of mass M/3 and radius R/2 is placed gently on the first disc coaxial. Then final angular velocity of the system is

Auniform disc of mass M and radius R is rotating in a horizontal plane about anaxis perpendicular to its plane with an angular velocity omega . Another disc of mass M/3 and radius R/2 is placed gently on the first disc coaxially. Then final angular velocity of the system is

A thin uniform circular disc of mass M and radius R is rotating in a horizontal plane about an axis perpendicular to the plane at an angular velocity omega . Another disc of mass M / 3 but same radius is placed gently on the first disc coaxially . the angular velocity of the system now is

A thin uniform circular disc of mass M and radius R is rotating in a horizontal plane about an axis passing through its centre and perpendicular to its plane with an angular velocity omega. another disc of the same dimensions but of mass M/4 is placed gently on the first disc coaxially. The angular velocity of the system now is 2 omega //sqrt5.
