Homework Help: Electric Potential problem, 4 equal charges, different signs, weird shape.

  1. Jan 15, 2010 #1
    1. The problem statement, all variables and given/known data
    The drawing shows four point charges. The value of q is 1.96 µC, and the distance d is 0.93 m. Find the total potential at the location P. Assume that the potential of a point charge is zero at infinity.
    Image of problem is attached.

    2. Relevant equations


    3. The attempt at a solution

    Our attempts at solving this problem included just adding the various vectors, canceling out the negative vectors since they pull in the opposite direction and just using the positive vectors, but neither works. Help? Problem due Tuesday by 11:30pm for homework. Thanks

    Hi BATBLady! :wink:

    Show us your full calculations, and then we can see what went wrong, and we'll know how to help! :smile:

    (btw, potential is a scalar, not a vector)
