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 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. 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 binary star system one star has thrice the mass of other. The stars rotate about their common centre of mass then :

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 period of rotation of the stars about their common centre of mass (in time of d ,m ,G) is .

A binary star has a time period 3 years (time period of earth is one year) while distance between the two stars is 9 times distance between earth and the sun. Mass of one star is equal to mass of the sun and mass of other is 20n times mass of the sun then calculate n .

A pair of stars rotates about a common centre of mass. One of the stars has a mass M and the other has mass m such that =2m. The distance between the centres of the stars is d ( d being large compare to the size of eithe star). The period of rotation of the stars about their common centre of mass ( in terms of d,m,G) is
