Asked by Saziye
A metal sphere is insulated electrically and is given a charge. If 50 electrons are added to the sphere in giving a charge, how many Coulombs are added to the sphere?

This question essentially comes down to how many Coulombs of charge 50 electrons have (i.e., the sphere, the initial charge, etc., are irrelevant). So, knowing that one elementary charge is
e = 1.6×10^-19 C
and that 50 electrons will have a total charge of -50e,
-50e × (1.6×10^-19 C/e) = -8.0×10^-18 C
e = 1.6×10^-19 C
and that 50 electrons will have a total charge of -50e,
-50e × (1.6×10^-19 C/e) = -8.0×10^-18 C
