JEE Advanced 2015 Discussion Forum › Mechanics questions › gravitation:}

one of the star of a binary(double) stars system is rotating in a circular orbit of radius r₁ with time period T. If the mass of this star is m₁ find the mass m₂ of the other star. Also find the distance between the two stars. Take m₁=20hrs
G=6.67*10^-11 N-m²/kg²
m₁=10³⁰kg
r₁=2.455*10⁶
(hint for the equation
(1+x)²=0.59 x³, x= approx 3)

He just posts questions with no effort from his side whatsoever; pay no attention to him. If you want, solve the problem for fun, but not here.
