Plastic rod rubbed with fur and glass rod rubbed with silk

Options

A. repel each other
B. mix up with each other
C. attract each other
D. None of the above

Explanation

To solve the problem regarding the interaction between a plastic rod rubbed with fur and a glass rod rubbed with silk, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Materials**:
- A plastic rod is rubbed with fur.
- A glass rod is rubbed with silk.

2. **Charge Transfer Mechanism**:
- When the glass rod is rubbed with silk, the glass rod loses electrons and becomes positively charged, while the silk gains those electrons and becomes negatively charged.
- Similarly, when the plastic rod is rubbed with fur, the plastic rod gains electrons from the fur and becomes negatively charged, while the fur loses electrons and becomes positively charged.

3. **Identifying Charges**:
- After rubbing:
- Glass rod: Positively charged
- Silk: Negatively charged
- Plastic rod: Negatively charged
- Fur: Positively charged

4. **Analyzing Interactions**:
- The glass rod (positively charged) will attract the negatively charged plastic rod.
- The silk (negatively charged) will repel the negatively charged plastic rod.
- The positively charged fur will repel the positively charged glass rod.

5. **Conclusion**:
- The glass rod and the plastic rod will attract each other due to opposite charges.
- Therefore, the interaction between the plastic rod rubbed with fur and the glass rod rubbed with silk will result in attraction.

### Final Answer:
The plastic rod (negatively charged) and the glass rod (positively charged) will attract each other.
