1. A glass rod with a charge of -5 nC is brought near to a metal sphere resting upon an insulatingstand. The sphere has a net charge of -3 nC. While the rod is kept near the sphere, a groundingwire is briefly connect to the sphere. What is the new, net charge on the sphere?2. A solid conductor with three, empty internal cavities has a net charge of +19 nC. If a +11 nCcharge is teleported into one of the cavities, what are two possible charges that could beteleported into the other cavities (one charge per cavity) such that the conductor has zero netcharge on its surface?

The electroscope is an apparatus used to detect electric charge. The electroscope consists of a plate, a support and thin metal foil that is free to deflect all made of metal. After rubbing a balloon on your sleeve, the negatively charged balloon is brought near to the metallic plate of an electroscope. As a result, the foil of the electroscope deflects. As the balloon approaches the electroscope, what is the net charge on the electroscope? Negative Positive Neutral Cannot be determined
