A disc of mass m and radius r is rotating with
angular velocity (!). Another disc of mass 2m
and radius r/2 is placed coaxially on the first
disc gently. The angular velocity of the system
is
5/2(!). 3/2(!). 2/5(!). 2/3(!)

Answer:
Since the angular moment will remain conserve, and the final angular velocity of both the disc will be same
2 MR 2
ω= 2 MR 2 ω 1 + 2(M/3)R
2ω 1So ω1 = 4 3ω
