1. The problem statement, all variables and given/known data The two metal plates of a capacitor are separated by a distance of 1mm. The electric field between the two plates is measured to be 100 N/C. If the capacitance is measured to be 5 uF, what is the magnitude of the charge on each plate, in Coulombs? 2. Relevant equations That's my problem as I can't find the appropriate equation. 3. The attempt at a solution Spent hours searching for the equation and now I'm too frustrated to continue.
