Problem 1: Electric field of charged plates Two charged plates are shown at right, with charge densities to. A. Recall that the field of a sheet charge is E = it points 280 away from positive sheets, and towards negative sheets. Use this to sketch a vector for the net field at each of the marked points. B. A student concludes the following: "The electric field at point C is zero, because the two charged plates have fields that cancel out." This student is incorrect. What mistake did they make? -0 XA 0 B C D -d- C. What is the magnitude of the net field between the plates? Use this to find the absolute value of the potential difference between the plates.
