A binary star consists of two dense sphereaty masses of 10rest power 30 kg and 2 x 10rest power 30kg. Whose centres are 10rest power7km apart and which rotate togethe with angula velocity w about an axis which intersects a line joining their centres - show that if the only forces acting on the stars are gravitational the axis of rotation passes through the center of man system - find the value of w.
