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. O eV -0.2 eV -0.4 eV- -0.6 eV -0.8 eV- -1.0 eV -1.2 eV -1.4 eVF -1.6 eVI (a) At r = r, what are the approximate values of the kinetic energy K, the potential energy U, and the quantity K+U? K = eV eV U = K+U= eV (b) What minimum (positive) amount of energy must be supplied to cause these two atoms to separate? eV
