In a double star, two stars (one of mass `m` and the other of mass `2m`) distance `d` apart rotate about their common centre of mass., Deduce an expressioin for the period of revolution. Show that te ratio of their angular momenta about the centre of mass is the same as the ratio of their kinetic energies.
