Question

A plastic rod that has been charged to -15.0nC touches a metal sphere. Afterward, the rod's charge is -10.0nC. How many charged particles were transferred?

Answer 1

Answer:

$3.125 X 10^{10}$

Explanation:

Net charge= -15.0 nC- -10.0 nC=-5nC

$\frac {-5 X 10^{-9}}{ -1.6 X 10^{-19}} = 3.125 X 10^{10}$ electrons were transferred
