1. The problem statement, all variables and given/known data The electric field strength 5cm from a very wide charged electrode is 1000N/C. What is the charge (in nC) on a 1cm diameter circular segment of the electrode? 2. Relevant equations E=Q/EoA n=Q/A 3. The attempt at a solution[/b I tried to figure out n, so that I can plug it into n=Q/A to figure out Q. But it didn't work.
