a) What is the general expression of force resulting from the L-J potential? b) At what value of the distance x does the potential have its minimum, if x0 = 0.34 nm? (Hint: how do you find a minimum or a maximum of a function y(x)? How do you make sure it is a minimum?)

a) What is the general expression of force resulting from the L-J potential?

b) At what value of the distance x does the potential have its minimum, if x0 = 0.34 nm? (Hint: how do you find a minimum or a maximum of a function y(x)? How do you make sure it is a minimum?)

One of the most important concepts in atomic and molecular physics is Lennard-Jones (L-J)
potential. It describes the potential energy of interaction of two atoms, U(x), depending on the
distance, x, between the atoms. The potential is expressed as follows:
U(x) = 4U. (2 -)
