I. A capacitor is comprised of two square parallel plates 4cm apart (each side lengthL = 0.5m). The capacitor is charged up, and the electric field between the two platesis E = 25000î V/m, as shown. You may assume the field is uniform and does notextend outside the plates (i.e., no fringing). A) What is the potential difference AV between the two plates? B) What is the total charge on the face of the right plate? C) What is the capacitance?
