Assertion: The gravitational field of moon is much less than that of earth.
Reason: Gravitational field of a given mass

(M)

depends upon

{M} / {r}^2

, which is smaller for moon.

View answer and explanation

Correct option: A

If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion

Option A (If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion) is correct because the moon's mass and radius are smaller than Earth's, resulting in a weaker gravitational field.
