Two stars in a binary system orbit around their center ofmass. The centers of the two stars are 7.90x 1011 m apart. The larger of the twostars has a mass of 3.40 x1030 kg, and its center is 2.30 x 1011 m from thesystem's center of mass. What is the mass of the smallerstar? ___________kg Two stars in a binary system orbit around their center ofmass. The centers of the two stars are 7.90x 1011 m apart.

Explanation / Answer
we have 3.40 x 1030*2.30 x 1011=x*(7.90 x 1011-2.30 x 1011) the mass of the smaller star x=1.4*1030 kg
