Hint 1 What tools from calculus do we have for finding the local extrema of a function? Hint Given a potential energy, how does one calculate its associated conservative force? The potential energy function for either one of the two atoms in a diatomic molecule is often b approximated by U(3) where + is the distance between the atoms. a. At what distance of separation does the potential energy have a local minimum (not at I - co)? Express your answer algebraically. Emin b. What is the force on an atom at this separation? (r = [min) =
