The electron typo was fixed, thanks for pointing it out. The answer is actually an integer - we were trying to give a hint/make it a little easier. However, I've changed it to be a float since it apparently was confusing some people which was not our intention.

lambda e / (2 pi epsilon) has an absolute value of 2.877 x 10^-9 J, i find it odd that the answer (in J) should be an integer on the interval [0, 999].

we're checking the numbers again. I'll post here when that's done.

Okay, problem has been slightly modified in the distance from the wire. Take a look again.

No wonder. Well since I submitted my solution (and 2 corrections to boot), I hope this will be taken into account (:

yep, I manually went back through everyone's submissions and fixed everything up. So all should be right now.
