X and Y are two uncharged metal spheres on insulating stands, and are in contact with each other. A positively charged rod R is brought close to X as shown in Figure (a). Sphere Y is now moved away from X, as in Figure (b). What are the final charge states of X and Y?
(a) X is positive and Y is neutral.
(b) Both X and Y are neutral.
(c) X is negative and Y is positive.
(d) Both X and Y are negative.
(e) X is neutral and Y is positive.
