Q:A homemade capacitor is built by placing two flat steel cookie sheets next to each other, with thin rubber spacers in between, so that they are separated by 1.25 mm. One sheet is given a positive charge of 7.93 C, and the other is given an equal and opposite negative charge. Each sheet measures 35.0 cm by 45.0 cm. (a) What is the strength of the electric field between the sheets? (b) If extra spacers are inserted to double the separation between the sheets, what is the new electric field strength? (c) If the sheets are moved a kilometer apart, the electric field between them becomes essentially zero. Explain the discrepancy between this result and the results observed in parts and of this problem.
