Question

Six electrons are in a two-dimensional square potential energy well with sides of length L. The potential energy is infinite at the sides and zero inside. The single-particle energies are given by where nxand nyare integers. If a seventh electron is added to the system when it is in its ground state the least energy the additional electron can have is:
A) 2(h2/8mL2)
B) 5(h2/8mL2)
C) 8 (h2/8mL2)
D) 10 (h2/8mL2)
E) 13 (h2/8mL2)
