An electroscope is a device that has small gold foil strips suspended from a metal rod. A student brings a negatively charged rod near the top of a neutral electroscope. The student then briefly touches a hand to the top of the electroscope before removing the charged rod. The foil strips of the electroscope now spread apart. The student then brings a different rod near the top of the electroscope. The leaves of the electroscope move closer together (see below). The new rod must have a net charge that is
1) positive.
2) negative.
3) neutral.
4) not enough information.
