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.
