In a binary star system in which 2 stars orbit each other about their centre of mass, the mass of one star is 20m while the other star is m. In another binary star system, the masses of the star are 14m and m. The fixed distance between the stars in the both cases are the same. Let v_1 be the velocity of 20m mass. Let v_2 be the velocity of the 14m mass. Find the exact value of v_1/v_2 ?
