Mass on Earth vs Mass on Moon

Explanation:

- The mass of a body is a measure of the amount of matter it contains. It is a scalar quantity and is usually measured in kilograms (kg).
- The mass of an object remains the same regardless of its location in the universe. So, the mass of a body on Earth will be the same as its mass on the Moon or any other celestial body. Therefore, the mass of the body will be 60 kg on both Earth and Moon.

Reasoning:

- The weight of a body, on the other hand, is a measure of the force of gravity acting on it. Weight is a vector quantity and is usually measured in newtons (N). The weight of an object can vary depending on the strength of the gravitational field it is in.
- The gravitational field on the Moon is about 1/6th of the gravitational field on Earth. This means that the force of gravity acting on a body on the Moon will be 1/6th of the force of gravity acting on the same body on Earth.
- The weight of a body can be calculated using the formula: Weight = Mass x Acceleration due to gravity.
- On Earth, the acceleration due to gravity is approximately 9.8 m/s^2. So, the weight of the body on Earth can be calculated as: Weight on Earth = 60 kg x 9.8 m/s^2 = 588 N.
- On the Moon, the acceleration due to gravity is approximately 1.6 m/s^2. So, the weight of the body on the Moon can be calculated as: Weight on Moon = 60 kg x 1.6 m/s^2 = 96 N.

Conclusion:

- The mass of a body remains the same regardless of its location. So, the mass of the body on Earth and Moon will be the same, which is 60 kg. However, the weight of the body will be different due to the difference in the strength of the gravitational field. The weight of the body on Earth is 588 N and on the Moon is 96 N. Therefore, the correct answer is option 'B' - 60 kg.
