Question

Figure 8-72a shows a molecule consisting of two atoms of masses mand M (withm<<M) and sparation r. Figure 8-72b shows thepotenial energy U(r) of the molecule as a function of r. Describethe motion of the atoms (a.) if the total mechanical energy E ofthe two atom system is greater than Zero (as is E1), and (b.) if Eis less than zero (as is E2). For E1=1*10^-19J and r=0.3nm, find(c.) the potential energy of the system, (d.) the total knineticenergy of the atoms, and (e.) the force (magnitude and direction)acting on each atom. For what values of r is the force (f.)repulsive, (g.) attractive, and (h.) zero?
