The force of gravitation between two bodies does not depend upon

Options

A. their separation
B. the gravitational constant
C. the product of their masses
D. the sum of their masses

Answer

To solve the question "The force of gravitation between two bodies does not depend upon," we need to analyze the gravitational force according to Newton's law of gravitation.

### Step-by-Step Solution:

1. **Understanding Newton's Law of Gravitation**:
According to Newton's law of gravitation, the gravitational force \( F \) between two point masses \( M_1 \) and \( M_2 \) separated by a distance \( r \) is given by the formula:
\[ F = G \frac{M_1 M_2}{r^2} \]
where \( G \) is the universal gravitational constant.

2. **Identifying the Dependencies**:
From the formula, we can see that:
- The gravitational force \( F \) is **directly proportional** to the **product of the masses** \( M_1 \) and \( M_2 \).
- The gravitational force \( F \) is **inversely proportional** to the **square of the distance** \( r \) between the two masses.

3. **Analyzing the Options**:
We need to determine what the gravitational force does not depend on. The key points from the formula are:
- It depends on the product of the masses \( M_1 \) and \( M_2 \).
- It depends on the distance \( r \) between the two bodies.
- It does not depend on the **sum of the masses** \( (M_1 + M_2) \).

4. **Conclusion**:
Therefore, the correct answer to the question "The force of gravitation between two bodies does not depend upon" is the **sum of the masses**.

### Final Answer:
The force of gravitation between two bodies does not depend upon the sum of their masses.
