Which of the following formulas correctly shows the relation between the gravitational potential energy between two objects with masses and , where their centers of mass are separated by a distance ?
The distance between the centers of mass of two massive objects is . If this distance is increased to , by what factor does the gravitational potential energy between the two objects change?
An asteroid with a mass of 3,500 kg moves from a position 40,000 km away from the center of mass of Earth to a position 22,000 km away. What is the change in the gravitational potential energy between the asteroid and Earth? Use a value of kg for the mass of Earth. Give your answer to 3 significant figures.
