The mass of the Earth is 5.98x10^24 kg, and the mass of the Moon is 7.36x 10^22 kg. The distance of separation, measured between their centers, is 3.84x10^8 m. Locate the center of mass of the Earth-Moon system as measured from the center of the Earth.
I tried using the formual r1=a m2/m1+m2) the answer i got was 4.67x10^6 but htis is not right.
