1. Consider the diagram below. a. A pair of insulated metal spheres, A and B, touch each other, so in effect they form a single uncharged conductor. b. A positively charged rod is brought near A, but not touching, and electrons in the metal sphere are attracted toward the rod. Charges in the spheres have redistributed, and the negative charge is labeled. Draw the appropriate + signs that are repelled to the far side of B. c. Draw the signs of charge when the spheres are separated while the rod is still present, and d. after the rod has been removed. Your completed work should be similar to Figure 22.7 in the textbook. The spheres have been charged by induction. 요요요요요요 d a 2. Consider below a single metal insulated sphere, (a) initially uncharged. When a negatively charged rod is nearby, (b), charges in the metal are separated. Electrons are repelled to the far side. When the sphere is touched with your finger, (c), electrons flow out of the sphere to Earth through your hand. The sphere is "grounded." Note the positive charge remaining (d) while the rod is still present and your finger removed, and (e) when the rod is removed. This is an example of charge induction by grounding. In this procedure the negative rod "gives" a positive charge to the sphere 요요 d b c The diagrams below show a similar procedure with a positive rod. Draw the correct charges for a through e. 외요 C
