The figure shows a potential energy curve for the interaction of two neutral atoms. The two-atom system is in a vibrational state indicated by the heavy solid horizontal line. (a) At r = r1, what are the approximate values of the kinetic energy K, the potential energy U, and the quantity K+U? K = (W U = eV K+U : eV (b) What minimum (positive) amount of energy must be supplied to cause these two atoms to separate? SW
