The Law of Gravitation was given by _____________.

Correct option is A

​The correct answer is (a) Isaac Newton

Explanation:

The Law of Universal Gravitation was formulated by Sir Isaac Newton in 1687 and published in his book Philosophiæ Naturalis Principia Mathematica.

According to Newton's Law of Gravitation:

​$$F = G \frac{m_1 m_2}{r^2}$$​​

where:

• F = Gravitational force between two objects
• G = Universal gravitational constant (6.674 × 10⁻¹¹ Nm²/kg²)
• m₁ & m₂ = Masses of the two objects
• r = Distance between the objects' centers

Key Insights About Newton’s Law of Gravitation:

• Explains planetary motion and how celestial bodies interact.
• Applies to all objects with mass, from small objects to massive planets.
• Forms the foundation for modern physics and space exploration.

Practical Applications of Newton’s Law:

• Understanding planetary orbits (e.g., Earth's revolution around the Sun).
• Designing satellites and space missions (e.g., ISRO & NASA calculations).
• Predicting tides due to the Moon’s gravitational pull.

Additional Knowledge:

• Darwin is known for theory of evolution and natural selection, not gravity.
• Einstein developed the Theory of General Relativity (1915).
• Galileo studied motion and free fall but did not formulate the law of gravitation.
