What is the value of 'G'?

Correct option is D

The correct answer is (d) 6.67 × 10⁻¹¹ N m² kg⁻²

Explanation:
• G is the gravitational constant in Newton's Law of Universal Gravitation.
• It is a fundamental constant of nature and is used to calculate the force of gravitational attraction between two masses.
• The value of G is approximately 6.67 × 10⁻¹¹ N m² kg⁻².
• The formula for gravitational force is given by:
F = G * (m₁ * m₂) / r²
where F is the gravitational force between two masses m₁ and m₂, and r is the distance between their centers.

Information Booster:
• The value of G is measured experimentally and is considered a universal constant.
• It is used to calculate gravitational forces between objects on Earth and in space.

Additional Knowledge:
9.99 × 10⁻¹⁹ N m² kg⁻² 
• This is not the correct value of G. It is too small and not related to the gravitational constant.

6.67 × 10⁻⁹ m sec⁻² 
• This value is incorrect as it represents acceleration, not the gravitational constant.

9.8 m sec⁻² 
• 9.8 m/sec² is the approximate acceleration due to gravity on Earth, not the gravitational constant G.
