Problem
Two identical isolated metal spheres A and B carry charges of +6.4μC and −1.6μC, respectively. They are connected by a thin conducting wire, allowed to come to equilibrium, and then disconnected. The number of electrons that flow through the wire during this process is approximately
(a) 5.0×1013 electrons flow from B to A
(b) 2.5×1013 electrons flow from A to B
(c) 2.5×1013 electrons flow from B to A
(d) 2.5×1012 electrons flow from B to A
