When two objects are charged through friction, the typical outcome is that they become oppositely charged due to the transfer of electrons from one object to another.
-
Equal and Opposite Charge: When one object loses electrons, it becomes positively charged, while the other gains those electrons and becomes negatively charged. The amounts of charge gained and lost are equal in magnitude but opposite in sign.
-
Different Amounts of Charge: It is also possible for the objects to end up with different amounts of charge. This can happen depending on the materials involved and how they interact with each other. Some materials might hold onto electrons more strongly than others, leading to an unequal distribution of charge.
Thus, the most accurate statement from your options regarding the behavior of charged objects through friction would be:
The objects become oppositely charged and have equal amounts of charge.
However, in practice, if considering all possible scenarios and materials, you might encounter situations where they become oppositely charged but with different amounts of charge. Therefore, while the most common result is equal and opposite charges, there are cases where different amounts of charge can result as well.
In summary, the answer that captures the fundamental behavior most accurately would be:
The objects become oppositely charged and can have different amounts of charge.
