Ideally, if you rub a balloon with your hair then and only then electron should transfer to the balloon surface, right? Why only by touching, non-conducting balloon gets electron on its surface? Clarify upon this please.
First question : Why even electrons are transferred to non-conducting balloon?
Second Question: I saw that when balloons are filled with air and you rub it with yourself, it would get negatively charged and I could stick them on the wall, but what happens if there is no air in balloon (freshly bought from store) and I still try to rub and place on the wall. Will it work? Why?
