Homework Help: Electric Dipoles

  1. Feb 4, 2009 #1
    1. The problem statement, all variables and given/known data
    Two opposite point charges of magnitude 1.90e-6 C are located near the origin. The positive charge is at (1.50, 1.50) mm and the negative charge is at (−1.50, −1.50) mm. What is the magnitude of the dipole moment vector for this pair of charges?

    2. Relevant equations
    p = qd
    d = sqrt(x^2 + y^2)

    3. The attempt at a solution
    I solved d = .002121
    solved p = 4.03051e.9

    Try calculating d again. It's the distance between the two charges.

    Also, including units with the values would be a good habit to get into.
