Given, weight on earth = 600 N
Since, W = mg
As, acceleration due to gravity (g) on earth ≈≈ 10 m/s2
So, 600 = m X 10
m = 60 kg
On moon weight of the man, W' = 100 N
Mass of the man will remain same on moon as that of the earth = 60 kg
Since, W' = m g'
where g' is the value of acceleration due to gravity on the moon
So, g' = W'/ m = 100/60 = 1.67 m/s2.

The weight and mass of a man on Earth and the Moon
To find the mass of a man, we need to understand the concepts of weight and mass and how they relate to each other. Weight is the force with which an object is pulled towards the center of the Earth (or any other celestial body) due to gravity, while mass is the amount of matter contained in an object.
Weight and mass on Earth:
Given that the weight of the man on the surface of the Earth is 588 Newtons and the acceleration due to gravity on Earth is 9.8 meters per second squared, we can use the formula: Weight = Mass * Acceleration due to gravity.
Therefore, 588 N = Mass * 9.8 m/s^2.
Calculating mass on Earth:
Rearranging the formula, we find:
Mass = Weight / Acceleration due to gravity.
Hence, the mass of the man on Earth is:
Mass = 588 N / 9.8 m/s^2 = 60 kg.
Weight and mass on the Moon:
Given that the weight of the man on the Moon is 98 Newtons, we need to calculate the acceleration due to gravity on the Moon and the mass of the man on the Moon.
Acceleration due to gravity on the Moon:
The acceleration due to gravity on the Moon is approximately 1/6th of that on Earth, which is 9.8 m/s^2. Therefore, the acceleration due to gravity on the Moon is:
9.8 m/s^2 / 6 = 1.63 m/s^2.
Calculating mass on the Moon:
Using the same formula as before, we find:
Mass = Weight / Acceleration due to gravity.
Hence, the mass of the man on the Moon is:
Mass = 98 N / 1.63 m/s^2 = 60 kg.
Summary:
- The weight of the man on Earth is 588 Newtons, and his mass is 60 kg.
- The weight of the man on the Moon is 98 Newtons, and his mass is also 60 kg.
- The acceleration due to gravity on the Moon is approximately 1.63 m/s^2, which is 1/6th of that on Earth.
