The potential energy of two atoms with a radius r is written as-
U(r)= -4Uo[(Ro/r)^12 -(Ro/r)^6]
Find the radius at stable equilibrium and the work required to separate the two atoms.
F(r) = -dU(r)/dr
The Attempt at a Solution
If found the stable equilibrium using the F(r) equation and setting it to zero. I have NO idea how to find the work.
A nudge in the right direction would be nice.
