Homework Help: Electrostatic Force Help!

  1. Oct 4, 2009 #1
    1. The problem statement, all variables and given/known data
    A Metal sphere has a charge of +6uC. What is the net charge after 1*10^14 electrons have been placed on it?

    2. Relevant equations
    Single Electron - -1.6*10^-19

    3. The attempt at a solution

    1st. Convert +6uC to 1.6*10^-6 (is this right???)
    2nd. (-1.6*10^-19)(1*10^14)=1.6*10^-5
    3rd. (6*10^-6)+(1.6*10^-5)= 2.2*10^-5 (?)

    I dont think this is a very hard problem but i want to make sure im doing the basics right. Thanks in Advance!

    No. Changing "micro" to 10^-6 is like moving a decimal point, without changing the digits. You can't change the 6 to a 1.6
