41. (a) The mass Mwithin Earth’s orbit is used to calculate the gravitational force on Earth. If ris the radius of the orbit, Ris the radius of the new Sun, and MSis the mass of the Sun, then MrRMs=FHGIKJ=××FHGIKJ×=×3111233025150 10590 10199 10327 10.....mmkgkgchThe gravitational force on Earth is given by GMm r2, where mis the mass of Earth and Gis the universal gravitational constant. Since the centripetal acceleration is given by
