A metal rod A and a metal sphere B, on insulating stands, touch each other as shown. They are originally neutral. First, a positively charged rod is brought near (but not touching) the far end of A. Then, while the charged rod is still close, A and B are separated. Finally, the charged rod is then withdrawn. At the end, the charge on the rod and sphere are _______________. It is NOT necessary to show work or reasoning for this problem.
