An object's mass and weight on Earth are 5 kg and 49 N. Taking the Moon's $g$ as 1/6th of Earth's, its mass and weight on the Moon are:

1. Mass is the amount of matter; it does not change with location, so it stays 5 kg on the Moon. 2. Weight is $W = mg$ and varies with $g$. 3. On the Moon $g$ is 1/6th of Earth's, so weight $= \dfrac{49}{6}$. 4. $\dfrac{49}{6} \approx 8.17$ N, giving 5 kg and 8.17 N. 5. Options that change the mass are wrong because mass is constant everywhere. _Source: Balbharati (Maharashtra Board) Class 10 Science & Technology, Ch 1 "Gravitation", p.24_
