Homework Statement
A metal sphere has a charge of +8.0 mirco coulomb. What is the net charge after 6.0x10^13 electrons have been placed on it.
Homework Equations
N=q/e or Coulombs Law F= k q1q2/r^2 e=1.6x10^-19
The Attempt at a Solution
Okay.well i know a mirco coulomb is 10^-6 So i figured you would multiply 8.0^-6 by 6.0^13 and then divide by electrons. But it doesn't seem to get the correct answer. The answer is -1.6 Mirco Coulombs but i don't know how to get that answer. It seems to be just mulitplication or divison, but i tired a 100 different ways, and i can't get -1.6Mirco Coulombs. Can someone help? Thank you!
