When a glass rod is rubbed with silk, it acquires a positive charge. According to the principles of electrostatics, objects with opposite charges attract each other, while objects with like charges repel each other.
Given that:
- Balloon 1 has a positive charge.
- Balloon 2 has a negative charge.
- Plastic sheet 1 has a negative charge.
- Plastic sheet 2 has a positive charge.
Since the glass rod is positively charged, it will attract both Balloon 2 (which has a negative charge) and Plastic sheet 1 (which also has a negative charge).
Therefore, the answer is that the rod will attract **Balloon 2 and Plastic sheet 1**.
Given that:
- Balloon 1 has a positive charge.
- Balloon 2 has a negative charge.
- Plastic sheet 1 has a negative charge.
- Plastic sheet 2 has a positive charge.
Since the glass rod is positively charged, it will attract both Balloon 2 (which has a negative charge) and Plastic sheet 1 (which also has a negative charge).
Therefore, the answer is that the rod will attract **Balloon 2 and Plastic sheet 1**.
