Finding the ground state energy of a particle

  1. Dec 2, 2012 #1
    For a particle with a force acting on it whose potential is given by U(x) = g*lnx for x>1 and U(x) = ∞ for x = 1, how do I calculate the ground state energy of the particle?

    Supposedly, there is no need to use Schrodinger's equations for this question, which is why I have no idea how to start.

    Thanks for any help.

    You should use the Schrödinger equation; which other ansatz do you have in mind?

    Alright, it must be a mistake then. We were given this question before learning the Schrodinger equation so it was impossible.

    Edit: would I just use boundary conditions to solve for E in the time independent schrodinger equation?

    The boundary condition is ψ(x=1) = 0
