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.
