Consider the plates of a parallel-plate capacitor. The upper plate has a charge density of o upper = 4.37 C/m2. a. What is the charge density, in coulombs per square meter, of the lower plate? b. Suppose that the charge on the lower plate is due to 10^19 free electrons. What is the area, in square meters, of the plate? c. What is the magnitude, in newtons, of the force on a single electron placed in the region between the plates?
