Homework Help: Bohr radii and energy

  1. Oct 16, 2008 #1
    1. The problem statement, all variables and given/known data
    An electron moves along a circular orbit in the potential U=1/2*k*r^2. Using Bohr's quantization condition, find the permissible orbital radii and energy levels of the electron



    2. Relevant equations
    L=mvr=n*hbar


    3. The attempt at a solution
    Will someone put me on the correct path. I understand how the coulomb force is used to derive the radii of the H atom, but I do not understand how to incorporate the given pot. fct.
    Thanks!

    incorporate the given potential in the following way:

    Do everything exactly as for the coulomb force, but instead of using the coulomb force use:

    \vec F=-\hat r \frac{d U}{dr}\;.
    [/tex]
