The correct option is (c).
Explanation
Newton's Universal Law of Gravitation states that every particle of matter in the universe attracts every other particle with a force. This force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers ($F = G \frac{m_1 m_2}{r^2}$).Statement-wise Analysis:
- Statement 1 is Correct: The law is "universal" because it applies to all bodies in the cosmos. It governs the motion of celestial bodies, such as the revolution of the Moon around the Earth and the planets around the Sun.
- Statement 2 is Incorrect: The law applies to all objects possessing mass, regardless of their size. It governs terrestrial objects (e.g., a falling stone) as well as celestial ones. While the gravitational force between small masses is extremely weak due to the small value of the gravitational constant ($G$), the law is still applicable.
- Statement 3 is Correct: Gravitational force is fundamentally attractive. Unlike electromagnetic forces, which can be attractive or repulsive depending on the charges involved, gravity always acts to pull masses toward one another.
Key Takeaway: The Universal Law of Gravitation applies to all matter in the universe, irrespective of mass or location, and the resulting force is always attractive.
