Question 134

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.
