Extracted text: 1. Two concentric metal sphere form a capacitor; the spheres are insulated from each other by mica having a dielectric constant of 6.0 and dielectric strength of 200 X 10 V/m. (a) Determine the capacitor value in terms of a (inner radius), b (outer radius), and E showing all your work. (b) What is the capacitor value if a = 5 cm and b= 5.5 cm. Assume the metal spheres have negligible thickness. (c) What voltage will need to be applied to cause breakdown between the inner and outer sphere? %3D
