A parallel-plate capacitor is made from two aluminum-foil sheets, each 3.90 cm wide and 10.3 m long. Between the sheets is a mica strip of the same width and length that is 0.0225 mm thick. What is the maximum charge that can be stored in this capacitor? (The dielectric constant of mica is 5.4, and its dielectric strength is 1.00 108 V/m.) Please help soon. I feel like this should have been easy, but its not.
