The graph above plots gravitational force versus distance for two asteroids of equal mass (10 billion kg). When the distance between the asteroids is 9,000 km, the gravitational force between them is about 82 N. Based on the trend shown in the graph, predict the force between the asteroids when the distance between them increases to 9,500 km.
A.
about 9,200 N
B.
about 90 N
C.
1,700 N
D.
about 74 N
