The two oppositely charged metal spheres in FIGURE Q26.10 have equal quantities of charge. They are brought into contact with a neutral metal rod. What is the final charge state of each sphere and of the rod? Use both charge diagrams and words to explain. What would happen if the neutral rod was made of glass, rather than of a metal?
Metal
FIGURE Q26.10
When both sphere A and sphere B are brought in contact with the metal rod the final the rod and both spheres will be neutral. This is because the metal rod is neutral and b have equal and opposite charges so the electrons will transfer through the metal rod reach static condition.
