A comet is moving in its orbit toward the Sun. As it approaches the Sun, part of the comet evaporates due to the Sun's heat. The comet and Sun exert a gravitational force, F, on each other. After six weeks, the comet and the Sun are one-eighth of their original distance apart, and the comet is one-fourth of its original mass. Which of the following is the force on the comet at the final distance?
