Dear student,

The disc with hole can be assumed to be a whole disc of radius 6m with its given mass, say M+ a disc of radius 1m whose center is at distance 3m from that of bigger disc and has mass ‘-m’

Since the mass distribution on both of them must be uniform,



The distance of center of mass of the system from the center of the larger disc will be
