1.	A thin uniform circular disc of mass M and radius R is rotating in a horizonatl plane about an axis passing through its centre and perpendicular to its plane with an angular velocity omega. Another disc of same thickness and radius but ofmass (1)/(8) M is placed gently on the first disc coaxially. The anuglar velocity of the system is now
