In this question would we have to account for the force exerted by the one semi-circular ring on the other????

The masses of two rings are different then the only change will be in the moment of inertia (I) part. Remaining part going to be the same.

And if the two parts are exerting any force on one another, then why we should bother about that? Do we need that?
