A binary star consists of two stars A (mass $$2.2\quad$$Ms) and B (mass $$11\quad$$ 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...
