Question

The mass of a body is $M$ on the surface of the earth, then its mass on the surface of the moon will be

• A. $\frac{M}{6}$
• B. $M$
• C. $M+6$
• D. $M\times 6$

Answer 1

The correct option is B

$M$

1. The mass of the body is an inherent property of a body and doesn't change anywhere.
2. While the weight will change.
3. The new weight, on the other hand, will be ${\frac{1}{6}}^{th}$of the original weight on earth as the acceleration due to gravity on the surface of the moon is ${\frac{1}{6}}^{th}$of that on the surface of the earth.
4. But the mass remains unchanged as it is constant universally.

Hence, option B is the correct answer.
