Intermolecular forces The potential energy function for either one of the two

Intermolecular forces The potential energy function for either one of the two atoms in a diatomic molecule is often approximated by U(x) = ax-12 - bx-6 where x is the distance between the atoms. x (a) What is the force as a function of separation distance? (b) At what distance of separation (xmin) does the potential energy have a local minimum (not at x = )? (c) What is the force on an atom at this separation?
