If the mass of body is M on the surface of the earth ,then its mass on the surface of the moon will be

Options

A. M
B. `M-6`
C. `M+6`
D. `Mxx6`

Explanation

To solve the question, "If the mass of a body is M on the surface of the Earth, then its mass on the surface of the Moon will be?", we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Mass**:
- Mass is a measure of the amount of matter in an object and is a scalar quantity. It does not change regardless of the object's location in the universe.

2. **Mass on Different Celestial Bodies**:
- The mass of an object remains constant whether it is on Earth, the Moon, or any other celestial body.

3. **Weight vs. Mass**:
- While mass remains constant, weight is the force exerted by gravity on that mass and can vary depending on the gravitational field strength of the celestial body. Weight is given by the formula:
\[ W = mg \]
where \( W \) is weight, \( m \) is mass, and \( g \) is the acceleration due to gravity.

4. **Acceleration due to Gravity**:
- The acceleration due to gravity on the Moon is different from that on Earth, but this does not affect the mass of the object.

5. **Conclusion**:
- Therefore, if the mass of the body is \( M \) on the surface of the Earth, its mass on the surface of the Moon will also be \( M \).

### Final Answer:
The mass of the body on the surface of the Moon will be \( M \).
