Question 4 Wire The figure provided shows a metal sphere hanging by an insulating thread within a hollow conducting sphere. A conducting wire extends from the metal sphere through a small hole in the hollow sphere, but without making contact with the metal sphere. A charged rod is then used to transfer positive charge to the protruding wire. After the charged rod has touched the wire and been removed, what is the charge of the outer surface of the hollow sphere? O Neutral O Negative O Positive
