The charge on the electroscope is opposite the charge on the charged strip, since when the strip is brought close to the top of the electroscope (but not touching), the vane. Clearly, by bringing a charged object close to an uncharged electroscope, transiently connecting the electroscope to a large uncharged conductor, and then removing the object, we can induce a charge of the opposite sign on the electroscope without affecting the charge on the object. tionand by means of induction. Similarly, the electroscope can be negatively charged by contact with a negatively charged object. Another neutral object (or ground) is brought in contact with the polarized object and the charges are transferred to the neutral object (or ground). The charge on the electroscope is opposite the charge on the charged strip, since when the strip is brought close to the top of the electroscope (but not touching), the vane. This shows how to do inductive charging. The leaf should hang at about 45°. In induction, what charge does a neutral substance gain compared to the object brought near it? 4.
