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)
