Thankfully for this particular problem I get to do the integration by software... kinda. Turns out to involve arctangent and a relative mess of symbols. Thanks for the suggestion about variables, it is definitely more clear that way.

Homework Statement Center a rod of length L at (0,0) with the length going horizontally. Take a point P at (0,y). Find the electric field at P. Homework Equations \lambda=Q/L E= \int k*dQ/R^{2} The Attempt at a Solution I am integrating from -L/2 to L/2 Since Q=lambda*L, I...

mC is generally millicoulomb, like the std prefix. Micro coulomb would generally be noted as uC, even if the u is a mu. To people trying to solve this, I believe Q3 goes in the position in which the electric fields from Q1 and Q2 are equal. E = (kQ)/(R^2)
