Homework Statement
A gas of neutral atoms is often modeled as an ideal gas, where the gas atoms are considered to be "elastic billiard balls" that only interact by bouncing off each other in a manner that conservers the total kinetic energy.
Homework Equations
V(r) = 4(Epsilon)[(delta/r)^12 - (delta/r)^6]
in dimensionless form
U(xi) = 4 [(1/xi)^12 - (1/xi)^6]
xi= delta/r, U = V(r)/epsilon
The Attempt at a Solution
so i differentiated V(r) to get F(r),since F(r) = - dV(r)/dr.The force at the minimum of the potential is zero and the potential minimum defines the equilibrium position of the system.
