Question

How much would a70kg man weight on the moon? What will be his mass on the earth and on the moon? [ g on moon = 1.7 m s ^ -2 ]​

Answer 1

$\fbox{\fbox{\large{\green{\mathfrak{Answer:-}}}}}$

Mass of the man, m = 70kg

$acceleration \: due \: to \: gravity \: on \\ \: moon. \: gm \: = 1.7 \: \: m \: \: {s}^{ - 2}$

Weight of the man on the moon, W = ?

From relation, W = mg

Putting values, we get,

$w = 70 \times 1.7 = 199 \: i.e. \: w \: = 199n$

The weight of the man on the moon will be 199N

The mass will remain same (70kg ) on earth and the moon.

Answer 2

Explanation:

weight of the man on moon will be

70*1.7 = 119 N

& weight of the same person on earth Wil l be

70*9.8 = 686 N

though his mass will remain same anywhere in the universe.
