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

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 :

A satellite of mass m is circulating around the earth with constant angular velocity. If the radius is R_(0) and mass of earth is M, then the angular momentum about the centre of the earth is

If a body of mass 'm' and radius of gyration K rotates with angular velocity omega , then the angular momentum of the body will be

A pair of stars rotates about their centre of mass One of the stars has a mass M and the other has mass m such that M =2m The distance between the centres of the stars is d (d being large compared to the size of either star) . The ratio of the angular momentum of the two stars about their common centre of mass (L_(m)//L_(m)) is .

In a double star system one of mass m_(1) and another of mass m_(2) with a separation d rotate about their common centre of mass. Then rate of sweeps of area of star of mass m_(1) to star of mass m_(2) about their common centre of mass is

In a double star, two stars (one of mass m and the other of mass 2m ) distance d apart rotate about their common centre of mass., Deduce an expressioin for the period of revolution. Show that te ratio of their angular momenta about the centre of mass is the same as the ratio of their kinetic energies.

In a double star system, two stars of masses m_1 and m_2 separated by a distance x rotate about their centre of mass. Find the common angular velocity and Time period of revolution.

Two stars of masses m_(1) and m_(2) distance r apart, revolve about their centre of mass. The period of revolution is :
