Calculate the position of the center of mass of the following pairs of objects. Use acoordinate system where the origin is at the center of the more massive object. Give youranswer not in meters but as a fraction of the radius as requested. Get data from insidethe front cover of your text.

Earth Radius = 6.37x10^6 m

Moon Radius = 1.74x10^6 m

Jupiter Radius = 1.90x10^7 m

Earth to moon distance = 3.84x10^8 m

earth to sun 1.496x10^11m

jupiter to sun 7.78x10^11 m

(a) The Earth and the Moon. Give the answer as a fraction of the earth's radius.

(b) The Sun and the Earth. Give the answer as a fraction of the sun's radius.

(c) The Sun and Jupiter. Give the answer as a fraction of the sun's radius.
