Homework Help: Electron in a hydrogen atom (uncertainty principle)

  1. May 24, 2009 #1
    1. The problem statement, all variables and given/known data

    For an electron in a hydrogen atom: in state psi(100):

    find (del-x)(del-p) where

    del x = integral of :[psi (x-<x>)2 psi]dv
    del p = integral of: [psi(p-<p>)2 psi]dv

    2. Relevant equations

    3. The attempt at a solution
    i attempted to multiply out both equations but i am not sure if this is the right way to go,
    assume the answer is something like (delx) (del p)>= h/2 ? but i am not sure how to get there?

    I suppose you could just do the integrals. BTW is p supposed to be px?
