Question 1 of 5

An infinite square well potential (one dimensional) whose width is W consists of seven non-interacting electrons. The mass of each electron is m and the spin of the electron is 1/2. What is the minimum energy required to collect all 7 electrons?

A

$22 \frac{\pi^{2} \hbar^{2}}{m W^{2}}$

B

$44 \frac{\pi^{2} \hbar^{2}}{m W^{2}}$

C

$11 \frac{\pi^{2} \hbar^{2}}{m W^{2}}$

D

$\frac{\pi^{2} \hbar^{2}}{m W^{2}}$
