Interaction Potential Energy

Postby Adam Kramer 1A » Sat Nov 16, 2019 2:06 pm

I remember Lavelle mentioning that interaction potential energy is proportional to -q1q2/r^6, but when I looked online, I found a lot of sources saying it was actually equal to kq1q2/r. Can someone explain the difference in the equations and why they are different, as well as which is more correct?

The formula, kq1q2/r, refer to the electric potential energy which finds the potential energy between two charges. While the formula, Dr.Lavelle talked about in class refers to the interaction potential energy which finds the potential energy between two atoms.

This is the potential energy for the intermolecular interactions rather the ones within a molecule.

What exactly do we need to know about it for Test 2?
