Each plate of a parallel-plate air-filled capacitor has an area of 0.0020 m2, and the separation of the plates is 0.020 mm. An electric field of 3.9x106 V/m is present between the plates. What is the surface charge density on the plates? HINT: (where E = electric field, V = Potential difference/Voltage, and d = distance between plates) Also note that 1 N/C = 1 V/m. (V/m is just another unit for electric field)
