An air-filled capacitor consists of two parallel plates, each withan area of 7.6 cm2, separated by a distanceof 1.70 mm.
(a) If a 17.0 Vpotential difference is applied to these plates, calculate theelectric field between the plates.
(b) What is the surface charge density?
(c) What is the capacitance?
(d) Find the charge on each plate.
