Homework Help: Electrostatics - Compute the electric charge

  1. Mar 7, 2009 #1
    1. The problem statement, all variables and given/known data
    three point charges q1,q2&q3 are place at the vertices of triangle as shown in the diagram charge q1 has been given 4.5 X 10^13 extra electrons, charge q2 given 9.0 X10^13 extra electrons and q3 has had 9.0 X 10^13 electrons taken from it. Calculate the electric charge of q1,q2,&q3?


    2. Relevant equations
    no,sorry..

    3. The attempt at a solution[
    1stly i use the formula V=u/q to find the charge but it doesn't work,so i'm stuck with it!!

    Re: Electrostatics..

    What's the charge per electron? (Look it up.)
