i can get the answer i should for a ball with radius 0.0800m and mass 1.00kg is attached to a rod 0.400m long in length to a second ball with radius 0.100m and mass 2.00kg. Where is the center of gravity of the system.(adsbygoogle = window.adsbygoogle || []).push({});

i used the formula Xcg = (M*R + m*r)/(M+m) and get an answer of 0.093 but the answer in the back of the book says i should get 0.387m from 1kg sphere. Am i using the correct formula?
