Question

If the potential energy between two molecules is given by $\mathrm{U}=\frac{\mathrm{A}}{\mathrm{r}^6}+\frac{\mathrm{B}}{\mathrm{r}^{12}}$, then at equilibrium, separation between molecules, and the potential energy are

Select the correct option:

$\left(\frac{2 B}{A}\right)^{\frac{1}{6}},-\frac{A^2}{2 B}$

$\left(\frac{B}{2 A}\right)^{\frac{1}{6}},-\frac{A^2}{2 B}$

$\left(\frac{2 B}{A}\right)^{\frac{1}{6}},-\frac{A^2}{4 B}$

$\left(\frac{B}{A}\right)^{\frac{1}{6}}, 0$
