Answer:
A
Step-by-step explanation:
The graph shows an exponential dependence between the distance for two asteroids and the gravitational force.
From the graph, the greater is distance, the smaller is gravitational force. The smaller is distance, the greater is gravitational force.
When the distance between the asteroids is 1,000 km, the gravitational force between them is about 6,700 N. When the distance decreases to 850 km (becomes smaller), the force becomes greater. Among given options, only option A shows greater gravitational force than 6,700 N.
