Option 1 states that gravitational force is experienced by all bodies in the universe. This means that every object, whether big or small, is subject to the force of gravity. This is correct as gravity is a fundamental force that acts on all objects.

Option 2 states that gravitational force is a dominant force between celestial bodies. Celestial bodies, such as planets, stars, and galaxies, experience strong gravitational attraction due to their large mass. This is true as gravity is the force responsible for keeping celestial bodies in orbit and governing the dynamics of the universe.

Option 3 states that gravitational force is a negligible force for atoms. At the atomic level, gravitational force is indeed very weak compared to other forces, such as electromagnetic force. It is often overshadowed by the stronger forces within atoms, and its effects are negligible in most cases. Therefore, option 3 is correct.

Option 4 claims that gravitational force is the same for all pairs of bodies in our universe. This statement is incorrect. Gravitational force depends on the mass of the objects and the distance between them. The force will vary depending on the mass of the bodies and their separation. Therefore, option 4 is the correct answer.
