Question

The mass of a man is 75kg.What will be his mass on surface of moon? Also calculate his weight on earth and moon

Answer 1

It is given that the mass of a man is 75 Kg in earth.

Then his mass would be same in moon as mass of anything cannot be changed.

The weight of the man in earth can be calculated by W=mg=75×9.8=735 N.

While g is gravitational force and has the value of 9.8 m/s2.

We know that a person weighs six times less on the moon than on the Earth.

As the Moon has one sixth of the gravity of Earth, his weight in moon would be 122.5 N.

Answer 2

Mass :- 75kg,  Weight:- ?,   Weight in moon:-?

W=mg   Let g be 9.8m/s^2

75 x 9.8

735N

Weight in moon= 1/6 Of Weight in earth

735/6 = 122.5N
