Electric Potential at a Point

  1. May 11, 2012 #1
    1. The problem statement, all variables and given/known data
    The diagram shows three charges, A (+5.0 μC),B (-7.0 μC), and C (+2.0 μC), placed at three corners of a rectangle. Point D is the fourth corner. What is the electric potential at point D?

    2. Relevant equations
    VEL = [itex]\frac{(k)(q1)}{d}[/itex]


    3. The attempt at a solution
    I don't know how to find it at Point D.
