i cant solve this and no engine can either

The interaction between two atoms of an inert gas element can be described by the Lennard-Jones potential with a dissociation energy ε=
17.4 meV and with an equilibrium separation of a0=0.3
nm (nanometers). Calculate the magnitude of the force necessary to reduce the separation from a0
to a
, 11% smaller. Give your answer in nN (nanonewtons, 10-9 Newtons).
please help me

The force required to reduce the separation is approximately 25.4 nN, directed to oppose the reduction.
