Finding the equilibrium distance Rsub0 using total energy.

  1. Oct 19, 2016 #1
    1. The problem statement, all variables and given/known data
    Using the total energy, solve for the equilibrium distance R0

    α is given and other constants such as permitivity ε0, avogrado, N, and charge q.

    2. Relevant equations
    Utotal=-Nα(q2/4piε0)(1-ρ/R0)

    3. The attempt at a solution
    Tried to plug the values but I can't solve for R0 since ρ is not given.

    I am confident that there was more to the problem statement than that.
