(i) (5 pts) Three spheres are observed in the two configurations below. Sphere 1 is a neutral conductor. Sphere 2 is either positively charged, negatively charged, or a neutral conductor. Note that none of the spheres are touching. From these observations draw the charges induced or present on spheres 1 and 2 below. + 1 2 2 Explain: (ii) (5 pts) Three point charges are stationary on an axis. The sign of the charge is indicated in the figure below, the magnitude of the charges are equal. In four separate experiments, you place a test charge in each of the four regions somewhere on the dashed line. In which of the four regions is it not possible for the net electric force on the test charge to be zero? (You may circle multiple answers.) I II III IV a) I b) II C) III d) IV Explain:
