When a glass rod is rubbed with a silk cloth, it becomes positively charged. To determine which items it would attract, we need to consider the properties of the objects in the context of electric charge.
-
Neutral Objects: A positively charged object will attract neutral objects because they will be induced to have a slight negative charge on the side nearest to the positively charged object. This means any neutral item would be attracted.
-
Negatively Charged Objects: A positively charged object will also attract any negatively charged items because opposite charges attract.
-
Positively Charged Objects: Positively charged items will repel the positively charged glass rod, meaning it will not be attracted to them.
Based on this reasoning:
- If balloon 1 is negatively charged, it would be attracted by the positively charged glass rod.
- If balloon 2 is neutral or positively charged, it would either be attracted or repelled depending on its charge status.
- Plastic sheet 1 and plastic sheet 2 need to be assessed similarly based on their charges.
Given this information, if we are looking for items that would be attracted to the positively charged glass rod:
- If balloon 1 is negatively charged, it would be attracted.
- If balloon 2 is neutral, it would be attracted.
- If plastic sheet 1 and plastic sheet 2 are neutral or negatively charged, they too would be attracted.
Without the actual images or specific details of the charge of each item, we can reasonably say that if balloon 1 is negatively charged and/or the other items are neutral, those would be the ones attracted to the positively charged glass rod.
Based on typical assignment structures, the correct answers may include:
A. balloon 1 (if it is negatively charged)
B. balloon 2 (if it is neutral)
C. plastic sheet 1 (if it is neutral)
D. plastic sheet 2 (if it is neutral)
Thus the answer could be E. balloon 1 and balloon 2 or more generally, all non-positively charged items would be included based on their charges.
