An object lying on Earth’s equator is accelerated (a) toward thecenter of Earth because Earth rotates, (b) toward the Sun becauseEarth revolves around the Sun in an almost circular orbit, and(c) toward the center of our galaxy because the Sun moves aroundthe galactic center.

Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This statement implies that the masses of the two stars are equal (see figure below). Assume the orbital speed of each star is V = 240 km/s and the orbital period of each is 12.1 days. Find the mass M of each star. (For comparison, the mass of our Sun is 1.99 x 1030 kg.) solar masses XCM M
