Work, Energy and Power

Question: The potential energy between two atoms in a molecule is given by $U(x) = \frac{a}{{{x^{12}}}} - \frac{b}{{{x^6}}}$; where a and b are positive constants and x is the distance between the atoms. The atom is in stable equilibrium when



1) $x = \sqrt[6]{{\frac{{11a}}{{5b}}}}$
2) $x = \sqrt[6]{{\frac{a}{{2b}}}}$
3) $x = 0$
4) $x = \sqrt[6]{{\frac{{2a}}{b}}}$
