Joseph is conducting an investigation on how two objects compare in mass, volume, and force with each other. When determining the  gravitational force between the two objects, the following characteristics of the objects should be considered :

MASS AND DISTANCE

Explanation:

The gravitational force is a force that attracts any two objects with mass. In fact, every object, including you, is pulling on every other object in the entire universe. This is called Newton's Universal Law of GravitationThe strength of the gravitational force between two objects depends on two factors, mass and distance. The force of gravity the masses exert on each other. If one of the masses is doubled, the force of gravity between the objects is doubled. increases, the force of gravity decreases.When two objects are gravitational locked, their gravitational force is centered in an area that is not at the center of either object, but at the barycenter of the system. The principle is similar to that of a see-saw.Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation.

Where are the options ?

The center is basically the heart of it
