Задача id12708

Two stars, under the influence of the force of their mutual gravitational attraction, describe circular orbits around their common center of mass with a period T equal to two years. The sum of the masses of stars is equal to two solar masses. Find the distance between the stars, knowing that the average distance from the Earth to the Sun is 150 · 106 km (the mass of the Earth is negligible compared to the mass of the Sun).
