An electrified glass rod, which has a positive charge, attracts a sleeve made of metal foil and suspended on a silk thread. What about the charge on the case?
Since the bodies are attracted, they either have a different sign (i.e. the sleeve is negatively charged), or one of the bodies is electrically neutral (i.e., the sleeve charge is 0).
