All objects anywhere on or near the earth are

-- Every object anywhere on or near the surface of the Earth is attracted toward the center of the Earth by a gravitational force whose strength is

(9.8 m/s²) · (the mass of the object, in kilograms)

The unit of the force is Newtons.

-- If the object is far from the surface of the Earth, then it is still attracted toward the center of the Earth by a gravitational force.  the strength of the force can be calculated with exactly the same formula, but the first factor will be less than (9.8 m/s²), and will depend on how far away the object is.

-- WHATEVER the strength of the force happens to be that attracts the object toward the center of the earth, ANOTHER force with exactly the same strength will always attract the Earth to the center of the object, no matter how far apart they are.  Even if the object is on the other side of the farthest planet in orbit around the farthest star in the farthest galaxy from Earth.

answer; i believe the correct answer is (40,000 j) good luck
