A one-dimensional square well of infinite depth and 1 Å width contains 3 electrons. The potential well is described by V = 0 for 0 < x < 1 Å and V = +o for a <0 and r > 1 Å. For a temperature of T 0 K, the average energy of the 3 electrons is E = 12.4 cV in the approxination that one neglects the Coulomb interaction between clectrons. In the same approximation and for T 0 K, what is the average energy for 4 electrons in this potential well?
