Parallel-Plate Capacitor: Two parallel square metal plates, 8.4 cm on each side, are 2.5 mm apart and carry equal but opposite charge uniformly distributed over their facing surfaces. How much excess charge is there on each plate if the electric field between the plates has a magnitude of 2.0 × 106 N/C? (k = 1/4??0 = 8.99 × 109 N ? m2/C2)
