The gravitational force between two bodies is :

Options

A. always repulsive
B. always attractive
C. attractive only at large distances
D. repulsive only at large distances.

Explanation

To solve the question regarding the nature of the gravitational force between two bodies, we will analyze the options provided and use the fundamental principles of gravitational force.

### Step-by-Step Solution:

1. **Understanding Gravitational Force**:
The gravitational force is defined as the force of attraction that exists between any two objects that have mass. This force is described by Newton's law of universal gravitation.

2. **Newton's Law of Universal Gravitation**:
According to this law, the gravitational force (F) between two masses (M and m) separated by a distance (r) is given by the formula:
\[ F = \frac{G \cdot M \cdot m}{r^2} \]
where \( G \) is the gravitational constant.

3. **Analyzing the Options**:
- **Option 1**: Always repulsive - This is incorrect because gravitational force is never repulsive; it always attracts.
- **Option 2**: Always attractive - This is correct as gravitational force always acts to pull masses toward each other.
- **Option 3**: Attractive only at large distances - This is incorrect; gravitational force is attractive at all distances.
- **Option 4**: Repulsive only at large distances - This is also incorrect; gravitational force does not become repulsive.

4. **Conclusion**:
Based on the analysis, the correct answer is **Option 2: always attractive**. The gravitational force between two bodies is always an attractive force.

### Final Answer:
The gravitational force between two bodies is always attractive.
