Question

The correct relation relating the potential energy U and r between two atoms is

• A. $U_{\left(r\right)}=\frac{A}{r^{12}}+\frac{B}{r^6}$
• B. $U_{\left(r\right)}=\frac{A}{r^{12}}-\frac{B}{r^6}$
• C. $U_{\left(r\right)}=\frac{A}{r^6}-\frac{B}{r^{12}}$
• D. $-U_{\left(r\right)}=\frac{K}{r^2}$

Answer 1

Answer: (B)

$U_{\left(r\right)}=\frac{A}{r^{12}}-\frac{B}{r^6}$

The Lennard-Jones Potential is given by the following equation:

$V=\frac{A}{r^{12}}-\frac{B}{r^6}$
