For a material with an ionic bond, the net potential energy between two adjacent ions, EN$,$ is modeled by the sum of attractive and repulsive energies. That is$,$

$=$ A$/$r $+$ B$/$r$^6$

$1.$Determine the equilibrium spacing distance r$0.$

$2.$ If the ions are separated apart to the distance of $1\mathrm{.}1$ r$0,$ what is the net force between the ions?
