Question

As in the video, we apply a charge + to the half-shell that carries the electroscope. This time, we also apply a charge – to the other half-shell. When we bring the two halves together, we observe that the electroscope discharges, just as in the video. What does the electroscope needle do when you separate the two half-shells again?
A) It deflects more than it did at the end of the video.
B) It does not deflect at all.
C) It deflects the same amount as at end of the video.
D) It deflects less than it did at the end of the video.

    Note: Although the video is not provided in this question, it is not needed to answer the question.

    Answer:

    B) It does not deflect at all

    Explanation:

    Since both half shells contain opposite charges, the two shells become electrically neutral when they are brought together and the electroscope discharges. On separating the two half shells again, the needle does not deflect because the half shells have now lost their charges to become neutral.
