The gravitational force between two objects is zero… a. when the two objects are not moving. b. when another object lies in-between the two original objects. c. when the distance between them becomes extremely large. d. at a location halfway between the two objects. me

C. when the distance between them becomes extremely large

Explanation:

The gravitational force between two masses is:

F = GMm / r²

where G is the universal constant of gravitation,

M and m are the masses of the objects,

and r is the distance between the objects.

As r grows very large, F grows very small.
