Particle in a 1-D box

  1. Jul 13, 2008 #1
    This seems a simple problem, but managed to confuse me and my friends a bit, it's definitely not a standard problem from the text-books.
    Regard a particle of mass m in a 1 dimensional box of length L (which can be seen as a infinitely deep potential well). What is the 'pressure force' on the wall? (please forgive me my vagueness, I translated this question from chinese).
    Thanks for your help!

    Calculate the energy levels. (This is pretty standard). Then calculate the pressure as P=-dE/dL. (In 3 dimensions it would be -dE/dV, where V=L3).
