a) Explanation Given data: Separation of the stars ‘ a’ is 20 million kilometres. The orbital period ‘ p’ is 4 days. Mass of the Sun ‘ M S u n ’ is 2 × 10 30 kg Formula used: The Newton’s version of Kepler’s third law for two-star system is p 2 = 4 π 2 a 3 G ( M 1 + M 2 ) M 1 + M 2 = 4 π 2 a 3 G p 2 ‘ M 1 + M 2 ’ sum of the masses of two stars in the binary system. ‘ G’ is the gravitational constant. ‘ a’ is the separation of two masses. ‘ p’ is the orbital period. Substituting the value of 20 million kilometres for ‘ a’ , 4 days for ‘ p’ and 6.67 × 10 − 11 N .m 2 /kg 2 for ‘ G’ , to find M 1 + M 2 M 1 + M 2 = 4 π 2 a 3 G p 2 M 1 + M 2 = 4× ( 3 .14 ) 2 × ( 20 million km ) 3 ( 6 .67×10 -11 N b) To determine The mass of unseen companion.
