In the hypothetical atomic interaction shown in figure C9.13, assume that the atoms initially have zero radial velocity at a separation of 0.25 nm. If the atoms are jostled slightly so that the system gains a slight amount of energy, what happens to the atoms’ separation afterward?
A. It oscillates within a small region about r = 0.25 nm.
B. It oscillates between r = 0.25 nm and r = 0.05 nm.
C. It directly increases toward infinity.
D. It eventually increases toward infinity, maybe directly but maybe after one detour to smaller separations.
E. So me other behavior (specify).
