Question

How many electrons will have to removed to give 1mico Columbus charge on a body?

Answer 1

Each electron has a charge of 1.6 x 10^-19 C, so to generate a charge of -1.2x10^-6 C you need 7.5x10^12 electrons. (To compute this number, divide the charge you need by the charge/electron to find the number of electrons needed).
