Two neutral metal spheres on wood stands are touching. a negatively charged rod is held directly above the top of the left sphere, not quite touching it. while the rod is there, the right sphere is moved so that the spheres no longer touch. then the rod is withdrawn. afterward, what is the charge state of each sphere? use charge diagrams to explain your answer.
a. both the spheres are neutral.
b. the left sphere is negatively charged, the right sphere is charged positively.
c. the right sphere is negatively charged, the left sphere is charged positively.
d. both the spheres are charged positively.
