A. How does quadrupling the distance between two objects affect the gravitational force between them? B. Suppose the Sun were somehow replaced by a star with twice as much mass. What would happen to the gravita tional force between Earth and the Sun? C. Suppose Earth were moved to one-third of its current distance from the Sun. What would happen to the gravi tational force between Earth and the Sun? 44. Allowable Orbits? A. Suppose the Sun were replaced by a star with twice as much mass. Could Earth”s orbit stay the same? Why or why not? B. Suppose Earth doubled in mass (but the Sun stayed the same as it is now). Could Earth”s orbit stay the same? Why or why not?
