Homework Help: Another seemingly very easy question (Energy)

  1. Dec 4, 2009 #1
    1. The problem statement, all variables and given/known data

    The diagram below is a graph of potential energy vs. interatomic separation for a particular diatomic molecule (that is, a molecule consisting of two atoms).


    For the energy level shown on the graph, imagine drawing a line whose length represents the kinetic energy when the interatomic separation is r0. This line runs from where to where?
    2. Relevant equations


    3. The attempt at a solution
    I always have problems analyzing graphs. I got the latter parts of this question correct which involved doing calculations. However, I can't seem to get this one. The only reasonable answer I can come up with is from 1 to 2 since that would make the molecule unbound and allow it to seperate (break apart). Any help on this question would be much appreciated.

    If you were to draw the total energy on the same graph as a function of r, what would it look like?
