1. The problem statement, all variables and given/known data A line of charge with a uniform density of 35.0 nC/m lies along the line y = -12.6 cm, between the points with coordinates x = 0 and x = 44.2 cm. Calculate the electric field it creates at the origin. Find the x- and y-components of the feild. 2. Relevant equations I beleive i have to use an integrated formula but im not sure which one. http://img385.imageshack.us/img385/8756/66883216ju0.png [Broken] 3. The attempt at a solution I'm not sure if i have the problem straight in my head, but if i do, then i dont know how to approach it. I know that i have to get the x and y components from the magnitude, and i know how to do that, but i don't really know how to find the magnitude.
