Homework Help: Depth of a finite square well

  1. Apr 11, 2012 #1
    1. The problem statement, all variables and given/known data

    A finite square well 2.0fm wide contains one electron. How deep must the well be if there are only two allowed (bound) energy levels for the electron?

    2. Relevant equations

    (1) E = [ a^2 * hbar^2 ] / 2m
    (2) u = sqrt [2m(E+Vo)] / hbar

    3. The attempt at a solution

    Use equation (1) to find E, a is the width
    Then use the E to find u in equation. Vo = 0 because it's in the box

    On the right track? Or completely off?
