answered-by-expert Expert Answer
Apply conservation of angular momentum
 
I1 w1=I2 w2
 
Initially MI Of the system(I1)= 1200+50*0=1200
 
Finally MI of the system=1200+50*22=1400.
 
Now one can easily find the answer.

A Uniform Disc of diameter R/2 is put over another uniform disc of radius R of same thickness and Density. The peripheries of the two discs touch each other. The Centre of Mass of the system from centre of the big disc is? (I asked this question before but the answer was wrong. They took the Radius as R/2 while it is the Diameter)
