By "see" I meant that I had checked my answer on the internet to see if I was correct in thinking that multipying the charge of an electron, charge of a proton, and k would yield the electrical force between an electron and proton. My answer was 23.10 x 10^-9 which seemed quite different than other answers I saw posted. Either my math was wrong or the numbers I have been using are wrong. I used -1.602 x 10^-19, 1.602 x 10^-19, and the k constant 9 x 10^9. Thanks!

Ok. If you used your calc to get 23E-9 from

9E9*1.6E-19*1.6E-19/(1E-10)^2

then you are right.

I don't know where you got the distance apart from, that of course can change the answer.
