Two large conducting plates on insulating stands are placed a distance D = 50 cm apart, as shown at right. The inner surface of one has a charge density of +0; the other, - The charge density on the outer surface of each plate is zero. a) Sketch the configuration of the plates as shown and draw field lines on your diagram to represent the electric field everywhere that a field exists. b) An electron is released at point 1 and accelerates to the right. When the electron reaches point 2, its horizontal component of velocity is equal to 1.45 x 10 m/s. Find the voltage difference between the two plates. c) Find the magnitude of the electric field at a point halfway between points 1 and 2. d) How much work must be done by an external agent to move an electron from rest at point 2 to rest at point 3?
