This problem explores the behavior of charge on realistic (i.e. non-ideal) insulators. We take as an example a long insulating rod suspended by insulating wires. Assume that the rod is initially electrically neutral. For convenience, we will refer to the left end of the A small metal ball is given a negative charge, then brought near (i.e., within a few millimeters) to end A of the rod. What happens to end A of the rod when the ball approaches it closely this first time? rod as end A, and the right end of the rod as end B (Figure 1). In the answer options for Select the expected behavior. this problem, "weakly attracted/repelled" means "attracted/repelled with a force of View Available Hint(s) magnitude similar to that which would exist between two balls, one of which is charged, and the other acquires a small induced charge". An attractive/repulsive force greater than this should be classified as "strongly attracted/repelled". strongly repelled strongly attracted weakly attracted O weakly repelled neither attracted nor repelled Submit Previous Answers X Incorrect; Try Again; 9 attempts remaining Now consider what happens when the small metal ball is repeatedly given a negative charge and then brought into contact with end A of the rod Part B After several contacts with the charged ball, how is the charge on the rod arranged? Select the best description. View Available Hint(s) positive charge on end B and negative charge on end A negative charge spread evenly on both ends negative charge on end A with end B remaining almost neutral O positive charge on end A with end B remaining almost neutral none of the above Submit Previous Answers X Incorrect; Try Again; 9 attempts remaining Figure Part C How does end A of the rod react when the ball approaches it after it has already made several contacts with the rod, such that a fairly large charge has been deposited at end A?
