1. The problem statement, all variables and given/known data A uniform line charge of density λ lies on the x axis between x=0 and x=L. Its total charge is 11 nC. The electric field at x=2L is (500 N/C)ˆı. Find the electric field at x=3L. Answer in units of N/C. 2. Relevant equations 3. The attempt at a solution I have no clue where to even begin...I know that eventually I need to obtain a relationship between E(2L) and E(3L) but besides that I'm totally lost.
