A parallel plate capacitor is constructed of two thin, washer-shaped, conducting plates as shown in the accompanying figure. Between the plates is a dielectric material as shown in the diagram above. The plates of the capacitor and the dielectric material all have an inner radius of a = 3.6 mm and an outer radius of b = 12.2 mm. The dielectric material has a thickness d = 1 mm and a relative permittivity of&, = 7.5. A potential of V = 6 Volts is applied to the top plate and the bottom plate is grounded. What is the capacitance of this structure? Enter your answer in units of picoFarads ( 10-12). V d ET a →→P
