Problem
Two identical small metal spheres A and B carry charges of +2.0μC and −5.0μC, respectively. They are connected momentarily by a thin conducting wire and then separated by a large distance.
(i) Find the common charge that each sphere finally possesses.
(ii) Determine the minimum number of electrons that flowed through the wire while the connection existed.
