Chapter 5.2, Problem 21E

To determine

(a)

To find:

The effect on the gravitational force under given conditions.

To determine

(b)

To find:

The value of $c$ and the gravitational force if the distance is $800$ kilometers.

To determine

(c)

To plot:

The graph of gravitational force versus distance between the centers of the asteroids for distances from $0$ to $1000\text{ kilometers}$ using the value of $c$ from part b, and the effect on the gravitational force when the distance between the asteroids is changed.
