Interaction potential energy

[claudia_1h]

In the slides from the last lecture, Dr. Lavelle wrote Ep is proportional to a1a2/r^6 and then 1/r^6. Are these both for interaction potential energy? Do they show different things?

I think the first equation where Ep is proportional to a1a2/r^6 is the real equation and the second equation where 1/r^6 was used to demonstrate the inverse effect that distance has on interaction potential energy.
