. The center of the moon is 0.0026 AU (3.890 x 108m) from the center of the Earth and has a relativemass of 0.0123.(a) (2 points).Locate the cm of the Earth-Moon system with respect to the center of the Earth. With respect to the center of the center of the Moon.(b) (2 points).Find the ratio of orbital velocities of the Earth and Moon about the cm of thesystem. If the orbital velocity of the Moon is 1012 m/s, what is the approximate orbital velocity of theEarth about the cm of the Earth-Moon system
