1. An air-filled capacitor consists of two parallel plates, each with an area of 7.06 cm2, separated by a distance of 1.28 mm. A 16.2 V potential difference is applied to these plates. Find the magnitude of the electric field between the plates. The permittivity of free space is 8.8542 × 10?12 C2 /N · m2.
2. Find the capacitance.
3. Find the magnitude of the charge on each plate.
