Answer:

8. The force of gravitation between two objects is less when...

a. the total of their masses is greater

b. the force of magnetism is greater

c. friction between them is greater

d. the distance between them is greater

Explanation:

Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

hope this helps
