Homework Help: Another question regarding potential.

  1. Jan 28, 2006 #1
    I have done this problem a few ways and can't seem to get the right answer. Any ideas?

    Figure 20-23 shows three charges at the corners of a rectangle of length x = 0.55 m and height y = 0.33 m. How much work must be done to move the three charges infinitely far from one another?

    Point charges are as follows: -3.3 microcoulombs in the bottom left, -6.1 microcoulombs in the top left, and 2.7 microcoulombs in the top right. Any ideas, as ive done this problem 4 times now and cant get the right answer?
