Problem

A small metal sphere has an initial net charge of +1.2×10−7 C+1.2\times10^{-7}\,\text{C}. Electrons can be transferred between the sphere and Earth through a thin conducting wire. Assume ∣qe∣=1.60×10−19 C|q_e|=1.60\times10^{-19}\,\text{C}. Determine the minimum whole number of electrons that must move to the sphere so that it becomes electrically neutral.
