41. (a) The mass M within Earth’s orbit is used to calculate the gravitational force on Earth. If r is the radius of the orbit, R is the radius of the new Sun, and M S is the mass of the Sun, then M r R M s = F H G I K J = × × F H G I K J ×= × 3 11 12 3 30 25 150 10 590 10 199 10 327 10 . . .. . m m kg kg c h The gravitational force on Earth is given by GMm r 2 , where m is the mass of Earth and G is the universal gravitational constant.
