Two circular plates with diameter 1.69 cm are used to form a parallel plate capacitor. The distance between the plates is 2.85 mm and the space between them is filled with air. Determine the magnitude of the electric field in this space when the capacitor is connected to a battery with a certain voltage that results in a charge of 2.40 pC on each plate.
