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 has a positive charge. e. Z is neutral (has no net charge.)
