D. Two students discuss what would happen if, instead of being uncharged, the conducting ball in part B had a small net charge. (Assume the ball and the tape are both positively charged.) Student 1: "Since the ball is a conductor, the excess charge will be evenly distributed on the surface. Since the ball and tape are positively charged, they will repel.' Student 2: "The tape will repel the positive charge on the ball and attract the negative charge on the ball. If the excess positive charge is not too much they may still attract each other." Student 1: "That can't be true. If the ball has a net positive charge then there is no negative charge on the ball." Do you agree with either student? Explain your reasoning.
