Electrical Fields Help

  1. Mar 30, 2009 #1
    1. The problem statement, all variables and given/known data

    How strong a field between plates 0.80 uf air gap capacitator if 2 mm apart has charge of 72 ucol?

    2. Relevant equations

    My teacher has not given a formula, any examples, etc. I really would like to learn this and its not in the text book. Please help, thanks.

    3. The attempt at a solution

    I won't lie because I have no clue.

    I also have a problem that says what is the magnitude and direction of the electrical field at a point midway between -8 ucoul and 7 ucol charge 8 cm apart? assume no other charges nearby.

    Try the equation that relates Q, C, and V.
