Question

Two particles of masses m1 and m2, m1 > m, move in circular paths under the action of their gravitational
attraction. While doing so, their separation remains constant and equals 'r' . Radius of circular path of m2 is:
​

Answer 1

Answer:

1. This is called as binary star system 2.As m1 is greater than m2 center of mass will be closer to m1. 3. Both the particles move in circular path due to mutual gravitational force of attraction basing their center of mass as center of rotation.
