Electrical potential problem

The problem is to find the potential at a point that is 3 meters away from two charges. (one 3 meters above, and the other 3 meters below)


I put that Ep=Epq1+Epq2



This gives me:


Which immediately set some bells off for me. Isnt that quite a bit of energy for a charge three meters away? By the same formula, Epq2 equals 17976J, for a total potential of 26964J. Maybe I am wrong, but it seems like a very high potential. I will admit that I havent wrapped my head around how large of charge a Coulomb is, so maybe 3μC and 6μC are very large amounts of charge, but something seems wrong to me…

Can someone take a look, and see if I did something wrong? Thank you.
