2) The mass of our sun is ~ 2 x 10^30 kg. The mass of a planet is 6 x 10^24 kg. If the

distance between the center-of-mass of each is 100 x 10^11 m, what is the distance

in meters from the center-of-mass of the sun to the center-of-mass of the Sun-

Earth system?

What should I use to go about this problem? Thanks!
