In a binary star system, two stars of masses m and 2m distance r apart are revolving about their common centre of mass under their mutual gravitational attraction. The ratio of angular momenta of two star about centre of mass is
The particles each of mass M, are located at the vertices of an equilateral triangle of side a. At what speed must they move, if they revolve under the influence of their gravitational force of attraction in a circular orbit, circumscribing the triangle while still preserving the equilateral triangle?
In a binary star system, two stars of masses m and 2m distance r apart are revolving about their common centre of mass under their mutual gravitational attraction. The ratio of kinetic energy of two stars is
