As in the video, we apply a charge + Q to the half-shell that carries the electroscope. This time, we also apply a charge - Q 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?

It deflects more than it did at the end of the video. It does not deflect at all. It deflects the same amount as at end of the video. It deflects less than it did at the end of the video.

David Vincent · Answer 1

When the positively charged half shell is brought in contact with the electroscope, its needle deflects due to charge present on the shell.

When the negatively charged half shell is brought in contact with the positively charged shell, the positive and negative charge present on each shell neutralises each other. So both the shells lose their charges. The positive half shell also loses all its charges

When we separate the half shells, there will be no deflection in the electroscope because both the shell have already lost their charges and they have become neutral bodies. So they will not be able to produce any deflection in the electroscope.
