DiscussionQuestions5. The gravitational force betweenthe Earth and Sun isA. about the same as the gravitational force betweenthe Moon and Sun because the Earth and the Moonare about the same distance from the Sun.B. larger than the gravitational force between theMoon and Sun because the Earth and the Moonare about the same distance from the Sun andthe Earth has a larger mass.C. smaller than the gravitational force between theMoon and Sun because the Earth and the Moon areabout the same distance from the Sun and the Earthhas a larger mass.D. Not enough information is given to determine whichis correct.
