Three pith balls supported by insulating threads hang from a support. We know that ball X is positively charged. When ball X is brought near balls Y and Z without touching them, it attracts Y and repels Z. Since pith is an insulating material, we can conclude that
 a. Y has a negative charge. b. Z has a negative charge. c. Y has a positive charge. d. Z is neutral (has no net charge.)
  e. Y is negatively charged or neutral (has no net charge.)
