In a certain binary star system, each star has the same mass as our sun. They revolve about their centre of mass. The distance between them is the same as the distance between earth and the sun. What is their period of revolution in years ?

In a certain binary-star system, each star has the same mass as our Sun, and they revolve about their center of mass. The distance between them is the same as the distance between Earth and the Sun. What is their period of revolution in years ?

In a double star system .Find w.

In a binary star system one of the stars has mass equal to mass of sun (M) . Separation between the stars is four times the average separation between earth and sun. Mass of the other star so that time period of revolution of the stars each other is equal to one earth year 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 particular double star system two stars of mass 3.22xx10^(30) kg each revolve about their common centre of mass 1.12xx10^(11) on away. (i). Calculate their common period of revolution, in years (ii). Suppose that a meteoroid (small solid particle in space) passes through this centre of mass moving at right angles to the orbital plane of the stars. What must its speed be if it is to escape from the gravitational field of the double star?

The small dense stars rotate about their common centre of mass as a binary system, each with a period of 1 year. One star has mass double than that of the other, while mass of the lighter star is one-third the mass of the Sun. The distance between the two stars is r and the distance of the earth from the Sun is R , find the relation between r and R .

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.

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
