# Yukawa Potential

Homework Statement:
Given in the picture
Relevant Equations:
None
So this is the problem:

My only point of confusion right now is in what the value of a is... I'm having trouble finding it anywhere, and online stuff about the yukawa potential just states that it's a parameter.

Thanks for any help!

Edit: It might be worth noting that gamma equals kq1q2.

Try reading the problem statement more carefully.

I guess I should have stated that my only guess is that it's the radius of gold, based on what it's saying, but i'm not confident in my guess.

I'm not sure how you're missing it, but the problem statement explicitly tells you the value of ##a##.

Oh wait.. is that A an angstrom??

Edit: I guess I really havent seen the symbol for an angstrom in a while... I thought it was some special value lol, thanks for dealing with this

Yes, but in your defense the symbol was badly rendered. It should've been Å.
