In the Hypothetical Atomic Interaction Shown in Figure C9 $\frac{1}{2} \mu|\vec{v}|^{2}=5 \times 10^{-21} J$

Multiple Choice

In the hypothetical atomic interaction shown in figure C9.13, suppose that initially the system's kinetic energy is $\frac{1}{2} \mu|\vec{v}|^{2}=5 \times 10^{-21} J$ at an initial separation of $0.1 \mathrm{~nm}$ . About how much energy would we have to add to the system for the atoms to fly off to infinite separation?

A) $1 \times 10^{-21} \mathrm{~J}$
B) $6 \times 10^{-21} \mathrm{~J}$
C) $11 \times 10^{-21} \mathrm{~J}$
D) $16 \times 10^{-21} \mathrm{~J}$
E) None. The atoms will do so without adding energy.
