Answer:
1.512 × 10^(30) kg
Explanation:
Distance between centre of the 2 stars: x_2 = 7.17 × 10^(11) m
Mass of larger star; m1 = 3.7 x 10^(30) kg
Distance of larger star from the system center of mass; x_cm = 2.08 × 10^(11) m
Let the initial distance be x1 = 0
Thus, to find the mass(m2) of the smaller star, we will use the formula;
m2 = m1(x_cm - x1)/(x_2 - x_cm)
Plugging in the relevant values, we have;
m2 = (3.7 x 10^(30)) × ((2.08 × 10^(11)) - 0)/((7.17 × 10^(11)) - (2.08 × 10^(11)))
m2 = 151.2 × 10^(28) kg = 1.512 × 10^(30) kg
