- Three particles lie on the x-axis: particle 1, with a charge of 1.27 μC is at 1.00 cm, particle 2, with a charge of 2.36 µC, is at x = 2.00 cm, and particle 3, with a charge of -3.41 μC, is at x = 3.00 cm. The potential energy of this arrangement, relative to the potential energy for infinite separation, is i J.
