Consider a capacitor consisting of two identical metal plates parallel to each other. Each plate has an area of 140 cm2 and they are separated by 2.7 mm. The space between the plates is filled with a dielectric material whose dielectric constant is 3.8. A voltage 8.5 V is applied across the plates.
(a) Find the capacitance of the capacitor.
(b) Find the magnitude of charge accumulated in one of the plates.
(c) Find the magnitude of the electric field between the two plates.
