(a)

To determine

Plot the graph of $U\left(r\right)$ and $F\left(r\right)$ Vs $r$.

(b)

To determine

Show the locations of points on graph of $U\left(r\right)$ and $F\left(r\right)$ Vs $r$ at which $U\left(r\right)=0$ and $F\left(r\right)=0$.

(c)

To determine

The values of $r_1$ and $r_2$ in terms of $R_{\text{o}}$ and also the ratio $\frac{r_1}{r_2}$.

(d)

To determine

The work that has to be done to pull the molecules at $r\to \infty$ apart.
