The potential Energy as a function of the force between two atoms in a diatomic 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 position of stable equilibrium for the system of the two atoms is given as:
- \(x=\frac{a}{b}\)
- \(x=\sqrt{\frac{a}{b}}\)
- \(x=\frac{\sqrt{3 a}}{b}\)
- \(x=\sqrt[6]{\left(\frac{2 a}{b}\right)}\)
Answer
(D) x= [6] ( 2 a b )
