Q: The weight of an object on the moon is equal to –––––– of its weight on the earth.
  • A. 1/8th
  • B. 1/6th
  • C. 1/10th
  • D. 1/4th
Correct Answer: Option B - The mass of the moon is 1/81 times and its radius 1/4 times that of earth. As a result, the gravitational attraction on the moon is about one-sixth when compared to earth. The moon’s gravitation force is determined by the mass and the size of the moon. Hence, the weight of an object on the moon is 1/6th its weight on the earth. The moon is far less massive than the Earth and has a different radius(R) as well.
