Correct option is C
The Correct Answer is: (c) 6.7 × 10⁻¹¹ N·m²/kg²
Explanation:
The Universal Gravitational Constant (G) is a fundamental physical constant that appears in Newton’s Law of Universal Gravitation.
The Universal Gravitational Constant (G) is a fundamental physical constant that appears in Newton’s Law of Universal Gravitation.
The law is given by:
Where:
- F is the gravitational force between two objects,
- m₁ and m₂ are their masses,
- r is the distance between their centers,
- G is the gravitational constant, with a fixed value of:
G=6.674×10−11Nm²/kg² (approximately 6.7×10−11Nm²/kg²)
Information Booster:
- G is constant throughout the universe and does not change with time or location.
- The unit of G is N·m²/kg² (newton meter square per kilogram square).
- It was first measured by Henry Cavendish in 1798 using a torsion balance.
- The gravitational constant is very small, indicating that gravitational force is weak compared to other fundamental forces.
