SUMMARY
The net charge on a metal sphere initially charged at +6 µC becomes +2.2 × 10^-5 C after adding 1 × 10^14 electrons. Each electron carries a charge of -1.6 × 10^-19 C, resulting in a total charge of -1.6 × 10^-5 C from the electrons. The calculation involves converting the initial charge from microcoulombs to coulombs and summing the charges correctly. The initial conversion of +6 µC to 1.6 × 10^-6 C is incorrect; it should remain as +6 × 10^-6 C.
