The gravitational constant depends upon

Options

A. Size of the bodies
B. Gravitational mass
C. Distance between the bodies
D. None of these

Answer

To answer the question regarding what the gravitational constant \( G \) depends on, we can analyze the properties of \( G \) and its nature in gravitational physics.

### Step-by-Step Solution:

1. **Understanding Gravitational Constant \( G \)**:
- The gravitational constant \( G \) is a fundamental physical constant used in the law of universal gravitation. It quantifies the strength of the gravitational force between two masses.

2. **Nature of \( G \)**:
- \( G \) is termed as a "universal" gravitational constant, which implies that it is the same throughout the universe. Its value does not change regardless of the location or the mass of the objects involved.

3. **Independence from Mass and Size**:
- The value of \( G \) does not depend on the mass of the bodies or their sizes. Whether we are considering small masses or astronomical bodies, \( G \) remains constant.

4. **Independence from Distance**:
- The gravitational constant \( G \) is also independent of the distance between the two masses. While the gravitational force between two masses does vary with distance (as per the inverse square law), \( G \) itself does not change.

5. **Conclusion**:
- Since \( G \) is a universal constant, it does not depend on any physical properties such as the size of the body, the mass of the body, or the distance between the bodies. Therefore, the correct answer to the question is that \( G \) does not depend on any of the given options.

### Final Answer:
The gravitational constant \( G \) does not depend on any of the listed factors (size of the body, gravitational mass, or distance between the two bodies). Thus, the correct option is **none of these**.
