I already know that a charged polyethylene plastic (done by rubbing it with paper) can be used to attract a cardboard. Now, can I 'charge' the cardboard by touching it with the plastic? Supposedly, the cardboard gets the same charge as the plastic, it would repel the plastic after I charge the plastic again and try to make contact with it.
Of course this is all hypothetical; I've actually tried it already and it doesn't work, thus I concluded that the cardboard cannot be charged this way. Probably because it is not a conductor.
Anyway, my question is, is there some scenario that the opposite happens and the cardboard gets the same charge as the plastic?
