The Attempt at a Solution
Not really sure on what to do. I am assuming we treat the objects like point masses but I'm not really sure on that either. Do you take the 1.2 kg object and only use this with its radius to each object? I tried but the answer wasnt in the answer options.
The 2 objects on the axis are confusing me. Where is the center of mass the object is rotating on.
Thanks for any help!
