The potential energy function for either one of the two atoms in a diatomic molecule is often approximated by U(x)=a/x^{12}-b/x^6U(x)=a/x 12 −b/x 6 where xx is the distance between the atoms. Find the distance of separation where the potential energy has a local minimum.

Acm ruler with main graduations from 1 to 10 from left to right there are 10 secondary graduations between each of the main graduations there is a line that begins. at the left end of the ruler 10 secondary graduations to the left of the “1 main graduation the right end of the line ends on the eighth secondary graduation to the right of 3 how long is the line
