On what two things does the gravitational force between two bodies depend?
ATheir charges and their separation
BTheir volumes and their temperatures
CTheir densities and their shapes
DTheir masses and their separation
Answer & Solution
Correct answer: D. Their masses and their separation
1. Gravitation is always an attraction, never a repulsion.
2. Its size is set only by the masses involved and by the distance between them.
3. Shape, temperature, charge and chemical make up play no part in the law.
4. That simplicity is why one formula holds everywhere in the universe.
