Two objects are sitting 150 meters apart and are not moving. Which best explains why the gravitational force does not cause them to move?

In the above pic question is similar like that only

The gravitational force between the two objects is weak because their masses are small

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
