D) The earth and the objects on earth
The law of gravitation applies to any pair of bodies. The Law of gravitation says that each and every particle attracts each and every other particle in the universe with the help of a force that is considered directly proportional to the product of their masses, and they are also inversely proportional to the square of the distance between their centers.
This law was given by Issac Newton, and it is also known as the ‘First Great Unification’. However, when Newton first presented it in Book 1 of the unpublished text in April in the year 1686 to the Royal Society, Robert Hooke made a claim that Newton had obtained the inverse square law from him.

Equation Of Law Of Gravitation
The equation for universal gravitation is-
where:
- F denotes the force between the masses;
- G denotes the gravitational constant (6.674×10−11 m3⋅kg−1⋅s−2);
- m1 denotes the first mass
- m2 denotes the second mass
- r denotes the distance between the centers of the masses.
Newton’s Law Of Gravitation Applies to:
Newton’s law of gravitation applies to all pairs of bodies in the universe. Newton’s gravity description is accurate for many practical purposes and is widely used. Any deviations from it are small when the dimensionless quantities ∅/c2 and (v/c)2 are much less than one, where ∅ is the gravitational potential,v2 is the velocity of the objects being studied, and C is the speed of light in a vacuum.
