The potential energy between two atoms in a molecule is given by `U(x)=(a/x^12)-(b/x^6)`, where a and b are positive constants and x is the distance between the atoms. find the distance between the atoms so that the molecule is in stable equilibrium

Options

A. `x= (a/(2b))^(1/6)`
B. `x= (2a/b)^(1/6)`
C. `x= ((11a)/(5b))^(1/6)`
D. x=0
