One description of the potential energy of a diatomic molecule is given by the Lennard-Jones potential,U =A/r¹² - B/r⁶ where A and B are constants and r is the separation distance between the atoms. For the H₂ molecule, take A= 0.124 × 10⁻¹²⁰ eV . m¹² and B = 1.488 × 10⁻⁶⁰eV . m⁶. = Find (a) the separation distance r₀ at which the energy of the molecule is a minimum
