A metal sphere is electrically neutral. It is touched by a positively-charged metal rod. As a result, the metal sphere becomes charged positively. Which of the following occur during the process? Select one or more: a. The metal sphere loses electrons. b. Positive electrons are moved between the two objects. c. Protons are transferred from the rod to the sphere. d. The overall charge of the system is conserved. e. The metal sphere gains some protons. f. Electrons are transferred from the sphere to the rod.
