Submit You have used 2 of 6 attempts Save HW 2.1.2 3.0/7.0 points (graded) Two 6.0-cm-diameter circular electrodes are spaced 5.0 mm apart. They are charged as shown where Q = 2.3 x 103 C. An electron is released from rest at the surface of the negative electrode. Based on the separation of the electrodes relative to their size, you can treat the electrodes as infinitely large sheets of charge. The electron has a mass of me = 9.11 x 10-31 kg and a charge of de =-1.6 × 10-19 C. Electron 1Q 2R 6.0 cm 目 5.0 mm a) What is the magnitude of the surface charge density on each of the electrodes?
