In walking across a carpet, you acquire a net negative charge of 50 MC (microcoulombs). How many excess electrons do you have?
An electron has a negative charge of 1.6 x 10^-19 C.
have,
q = ne
n = q/e
= 50 mC x 10^-6 / 1.6 x 10^-19
= 3.1 x 10^14 electrons
Is my work/answer correct for this question?
