A point charge q= 4.00 nC is placed at the origin, and a second point charge q -3.00 nC is placed on the x-axis at x=+20.0 cm. A third point charge q3 2.00 nC is to be placed on the x-axis between qi and q2. Let the potential energy of the three charges be zero when they are infinitely far apart. What is the potential energy of the system of the three charges if qs is placed at x =+10.0 cm?
