A B field is applied out of the page. Due to magnetic forces on the charge carriers, the bottom of the slab is at a higher electric potential than the top of the slab. I B V > V(Top) On the basis of this experiment, the sign of the charge carriers that make up the current in the slab is: 1) positive 2) negative 3) cannot be
