The planet Tatooine has a mass m and is unusual in that it orbits two stars. The larger of the two stars has mass 1634m and travels in a circle of radius R. The smaller star has mass 9m and travels in a circle of radius 5R . Tatooine itself travels around these two stars in a circular orbit of radius 11 R. Once in a life cylce, Tatooine and both stars align as indicated in the diagram below. For simplicity, assume all three orbits are centered on the origin. Required:
Calculate the magnitude of the net force acting on the planet Tatooine.
