A binary star consists of two stars `A(mass 2.2 M_s)` and B `(mass 11 M_s)` where `M_s` is the mass of the sun, they are separted by distane d and are rotating about their center of mass, which is stationary. The ratio of the total angular momentum of the binary to the angular momentum of star B about the centre of mass is

A binary star consists of two stars A (mass 2.2M_(s) ), and B of mass (11M_(s)) where M_(s) is the mass of the sun. They are separated by distance d and are rotating about their centre of mass, which is stationary. The ratio of the total angular momentum of the binary start to the angular momentum of star B about the centre of mass is

The angular momentum of the atom about the centre of mass will be

The angular momentum of the atom about the centre of mass will be

Two stars of masses m and 2m at a distance d rotate about their common centre of mass in free space. The period of revolution is :
