1. The problem statement, all variables and given/known data See image 2. Relevant equations KQ/r^2 3. The attempt at a solution I have seen several different ways of working this problem, but they have all failed on me. I tried this using the equation above from my book E = (8.99x10^9)(1036 C)/(4x10^-6m) E= 2.328x10^18 N/C I also tried using E = K*Q/sqrt(r^2+(L/2)^2) E = 1.86x10^11 N/C This was not correct. Please help. Thanks in advance!
