Homework Help: Electric dipole moment question

  1. Mar 1, 2009 #1
    1. In an electric dipole moment, assume that both charges are positive and find the electric field "E" at point "P", assuming X>>d, where "d" is the distance between the two charges and "X" is the distance of point "P" from the center of the dipole.

    I have thought a lot about it but I am very much confused. Any help will be greatly appreciated.

    Thanks

    Okay, well let's start with the definition of an electric dipole - what is it?

    "a pair of equal and opposite electric charges or magnetic poles separated by a small distance".

    I was also thinking that we cannot assume that both charges are positive, but my teacher gave me this question as an assignment. I thought that may be there is a solution for this. So confused!!!
