Homework Help: Charge position

  1. Jul 6, 2010 #1
    1. The problem statement, all variables and given/known data

    A 6μC charge is placed at the origin and a -10μC charge is placed on the x-axis at x = 5cm.
    Locate the position on the x-axis where the electric field is zero.

    2. Relevant equations

    3. The attempt at a solution

    6/16 * .05 = .01875

    I have no idea if this attempt is right, thanks for any help

    That seems to be just some random calculation involving the given quantities. Sorry, no, it's incorrect.

    Reading this question, I see the key phrases "charge" and "electric field". Check your book or class lecture notes for any equations that relate those things. That would be a start towards solving this one.
