Electric dipole

  1. Oct 12, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider the charge configuration described where two equal but opposite charges of magnitude Q. What is the magnitude of the electric field and the electric potential from the dipole as a function of the distance x from the center of the dipole perpendicular to the dipole moment?

    2. Relevant equations

    V= k[tex]\sum[/tex]qi/ri

    3. The attempt at a solution

    E= (2aq cos[tex]\theta[/tex])/(4[tex]\pi[/tex][tex]\epsilon_0[/tex]r^2)

    V=( P cos[tex]\theta[/tex])/(4[tex]\pi[/tex][tex]\epsilon_0[/tex]r)

    is this totally wrong?
