How does the value of the Universal Gravitational Constant (G) change if an object is moved from the Earth to the Moon?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. It increases.
  2. It remains constant.
  3. It decreases.
  4. It becomes zero.

Correct answer and explanation

Correct answer: It remains constant.

Explanation: ✅ Correct Answer: B) It remains constant. 📚 Explanation: It is vital to distinguish between 'g' (acceleration due to gravity) and 'G' (Universal Gravitational Constant). While 'g' changes depending on the mass and radius of a planet, 'G' is a fundamental physical constant that remains the same throughout the entire universe. Its value is approximately 6.67 × 10⁻¹¹ N m²/kg² regardless of the location.
