Ok, this is not really homework so maybe it needs to be moved some where else.
Made a basic electroscope out of a wine bottle a while ago, charged up a balloon brought it close to the end of the scope and the leaves separated as expected, but when I quickly moved the balloon away from the scope the leaves separated 5 times wider for a few seconds then fell back. Why is this, is it due to some sort of sudden charge backwash in the process of depolarisation (is that a term :/) ?
Thx
