1. The problem statement, all variables and given/known data The potential energy of two atoms separated by a distance r may be written as: U(r) = 4Uatomic * [(r0/r)12 - (r0/r)6] >Given r0 = 4.0 Ao and Uatomic = -0.012795 eV, what is the distance at which there is no net force between the atoms? Express your answer in terms of Ao. >What is the potential energy at the position where the net force is 0 N? Express your answer in terms of eV. 2. Relevant equations The above equation. 3. The attempt at a solution I tried using Coulomb's Law, but I don't know the charges so it's not very helpful. Finding the total energy is also not relevant since I don't know mass or velocity. I'm pretty stuck here. I know once I find the first part I can find the second part easily, but I feel like I'm overlooking something simple for the first part of the question.
