N = number of electrons, e = charge of one electron, Q = total charge.N = Q/e = -3.5x10^-6 C/(-1.60217646 × 10-19 C) = 2.......

Charge of one electron is -1.60217646 × 10-19 C

-3.5μC = -3.5x10^-6 C

Ne = Q
N = number of electrons, e = charge of one electron, Q = total charge.

N = Q/e = -3.5x10^-6 C/(-1.60217646 × 10-19 C) = 2.2 x 10^13 electrons
