moves parallel or normal to their common line. However the mutual momentum is always in the plane containing, the two charges and the direction of motion. For more than two charges, the mutual effect may be treated as the sum of the effects for all possible pairs, due to the quadratic property of the momentum and energy. The foregoing results have application in the study of "packing effect" in atomic structure.
