Question

A binary star consists of two stars A (mass 2.2 MS ) and B (mass 11 MS ), where MS is the mass of the sun. They are separated by distance d and are rotating about their centre of mass, which is stationary. The ratio of the total angular momentum of the binary star to the angular momentum of star B about the centre of mass is:-

Answer:

6

Solution:

$\frac{L _{total}}{L _{B}} = \frac{m _{1} r _{1}^{2}}{m _{2} r _{2}^{2}} + 1$ \end{document}
