The value of G at the moon as compared with its value at the earth is :

Correct answer: B. Same

  • A. Smaller
  • B. Same
  • C. Greater
  • D. Zero

Explanation

The gravitational constant G is a fundamental constant of nature that expresses the strength of gravitational attraction between two masses. It is a universal constant, meaning it remains the same throughout the universe. Thus, the value of G is the same on the Moon as it is on Earth, or anywhere else.Options A, C, and D are incorrect because they suggest G can vary based on location, which contradicts the definition and understanding of G as a universal constant.

About Law of Universal Gravitation

Every two masses attract each other with a force proportional to the product of their masses and inversely proportional to the square of their separation, expressed as F = Gm₁m₂/r². Questions also involve the gravitational constant, vector direction, superposition of gravitational forces, and the distinction between gravitational force and gravitational field strength.
