Which one of the following statements about gravitational force is NOT correct ?
Explanation
Newton's Law of Universal Gravitation states that every particle of matter in the universe attracts every other particle with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Consequently, gravitational force is experienced by all bodies in the universe. It is the dominant force governing the motion of celestial bodies like planets, stars, and galaxies [1]. However, because the gravitational constant (G) is extremely small, gravity is the weakest of the four fundamental forces and is considered a negligible force for atoms and subatomic particles [1]. Statement 4 is incorrect because the magnitude of the force depends specifically on the masses of the two bodies and their separation distance; therefore, it varies significantly between different pairs of bodies rather than being the same for all.
