If mass of a man is 60 kg on earth, what will be his weight on the moon?

Concept:

- As the mass of the moon is 1/100 times the mass of Earth and radius of the moon is ¼ times the radius of the Earth

- As a result, the gravitational attraction on the moon is about one-sixth when compared to that of the Earth

- The weight of an object depends on the value of acceleration due to gravity g

- Hence the weight of an object on the moon is 1/6th of the weight on the Earth

Calculation:

Weight on Earth = mg = 60 × 9.8 N

Weight on Moon:

$({W_m} = \frac{1}{6}{W_E} = \frac{1}{6} \times 60 \times 9.8 = 10 \times 9.8 = 98\;N)$
