Question

$\text{Assertion}$: A balloon filled with hydrogen will fall with acceleration $\frac{g}{6}$ of the moon.
$\text{Reason}$: Acceleration due to gravity is $\frac{g}{6}$ on the surface of moon.

• A. If both assertion and reason are correct and the reason is the correct explanation of the assertion.
• B. If both assertion and reason are correct and the reason is not a correct explanation of the assertion.
• C. If the assertion is correct but reason is incorrect.
• D. If the assertion is incorrect but reason is correct.

Answer 1

The correct option is A If both assertion and reason are correct and the reason is the correct explanation of the assertion.

A balloon will not experience any buoyant force on the moon because it has no atmosphere, so it will have free fall under gravitational pull of the moon with acceleration equal to $\frac{g}{6}$.
