It's Just Math 1

The problem: A proton approaches a long line of positive charge so that with its initial trajectory, it would intersect the line. The line has a uniform charge density of 5 nanoC/m. If the proton starts off with a velocity 300 km/s, a distance 1 km from the line charge, what is the distance of the closest approach? Hint: find the field and potential that affect the proton. Given: Mass of proton = 1.67E - 27 kg; K = 8.99E9 Nmm/CC.

Math is my least favorite subject in the world...but I think the person who did this dislikes it even more than I do.

His/her solution:
