If two metalic balls are placed in space, where the weight of the balls is zero, then_________

Options

A. they move towards each other.
B. they repel each other.
C. they remain in their position.
D. We cannot say anything about their status.

Explanation

### Step-by-Step Solution

1. **Understanding the Concept of Weight in Space**:
- In space, the weight of an object is zero when it is far from any gravitational influence, like planets or stars. This means that the objects are in a state of free fall or weightlessness.

2. **Identifying the Properties of the Metallic Balls**:
- The two metallic balls have mass. Even though their weight is zero, they still possess mass, which is a fundamental property of matter.

3. **Applying Newton's Law of Gravitation**:
- According to Newton's law of gravitation, any two objects with mass exert a gravitational force on each other. This force is always attractive, meaning that the two metallic balls will pull towards each other.

4. **Determining the Motion of the Balls**:
- Since there is an attractive force between the two balls due to their mass, they will move towards each other. This movement occurs because there is no other force acting on them to keep them apart.

5. **Conclusion**:
- Therefore, if two metallic balls are placed in space where their weight is zero, they will move towards each other due to the gravitational attraction between them.

### Final Answer:
If two metallic balls are placed in space, where the weight of the balls is zero, then they will move towards each other due to their gravitational attraction.
