In the given situation where Jeff puts on a leather jacket over his sweater and the sweater becomes negatively charged, we need to identify the correct statements that explain why the sweater became negatively charged.
1. The sweater has a tendency to attract electrons.
- This statement is correct because certain materials, like the sweater in this case, have a tendency to attract electrons when they come in contact with other materials. This can lead to a negative charge on the sweater.
3. The leather jacket has a tendency to attract electrons.
- This statement is incorrect. Leather, as a material, does not have a significant tendency to attract electrons. Therefore, the leather jacket is not the cause of the sweater becoming negatively charged.
5. The leather jacket has a lower tendency to attract electrons than the sweater.
- This statement is incorrect. Since the leather jacket does not attract electrons significantly, it cannot be compared to the sweater in terms of its tendency to attract electrons.
Therefore, the correct statement that explains why the sweater became negatively charged is:
- The sweater has a tendency to attract electrons.
