If the potential energy between two molecules is given by {\U}=-{{\A}}/ {{\r}^{6}}+{{\B}}/{{\r}^{12}}, then at equilibrium, separation between molecules, and the potential energy are : [6 Sep 2020 Shift 1]

Correct Answer is : (2BA)16,−A24B

({{\B}}/{2 {\A}})^{1 / 6},-{{\A}^{2}}/{2 {\B}}

({{2\B}}/{ {\A}})^{1 / 6},-{{\A}^{2}}/{4 {\B}}

({{2\B}}/{ {\A}})^{1 / 6},-{{\A}^{2}}/{2 {\B}}
