A 10 cm × 10 cm piece of aluminum foil of 0.1 mm thickness has a charge of 20 μC that spreads on both wide side surfaces evenly. You may ignore the charges on the thin sides of the edges. (a) Find the charge density. (b) Find the electric field 1 cm from the center, assuming approximate planar symmetry.
