Electrostatics and Coulomb's law

  1. Feb 14, 2012 #1
    1. The problem statement, all variables and given/known data
    +2μC -2μC
    0------------0
    | |

    0------------0
    +2μC -2μC
    This is a square
    Each side in .2 (no units)
    Find the magnitude and direction of the electric field at the center of the square

    2. Relevant equations

    E=F/q
    E=kq/r^2



    3. The attempt at a solution
    E=kq/r^2
    E= 9E9 * 2E-6/√.02^2
    E=900,000 N/C

    I am pretty confident in this answer but i do not know how to find the direction of this field
