An electroscope is given a positive charge, \( \| \) causing its foil leaves to separate. When an object is brought near the top plate of the electroscope, the foils separate even further. We conclude
(1) that the object is positively charged
(2) that the object is electrically neutral
(3) that the object is negatively charged
(4) none of these
