When a glass rod is rubbed with silk, it becomes positively charged. This positively charged rod will attract negatively charged items or neutral items due to polarization.
- Balloon 1: If this balloon is negatively charged, it will be attracted to the positively charged glass rod.
- Balloon 2: If this balloon is also negatively charged, it will also be attracted to the glass rod.
- Plastic sheet 1: If this sheet is negatively charged, it will be attracted to the rod.
- Plastic sheet 2: If this sheet is negatively charged, it will also be attracted to the rod.
Without the specifics of the charge of Balloon 1, Plastic sheet 1, Balloon 2, and Plastic sheet 2, the most general answer would be:
- If Balloon 1 or Plastic sheet 2 is negatively charged, then either of them or both will attract the positively charged glass rod.
Therefore, the answer may be:
- Balloon 1 and Plastic sheet 2, if they are both negatively charged.
- If you only know that one of them is negatively charged, then that one will attract it.
Based on common charges, it’s likely that:
- Balloon 1 and Plastic sheet 2 will be the correct attraction.
If you can clarify the charges or other details about the items, I could provide a more precise answer!
