प्रश्न

The mass of moon is about 0.012 times that of earth and its diameter is about 0.25 times that of earth. The value of G on the moon will be:

विकल्प

  • less than that on the earth

  • more than that on the earth

  • same as that on the earth

  • about one-sixth of that on the earth

MCQ

उत्तर

Same as that of the earth
G is universal gravitational constant. So, it remains constant everywhere.
