A point charge q_1 = 4.00 nC is placed at the origin, and a second point charge q_2 = -3.00 nC , placed on the x-axis at x = + 20.0 cm. A third point charge q_3 = 2.00 nC is placed on the X-axis between q_1, and q_2 . (Take as zero the potential energy of the three charges when they are infinitely far apart).
