In the figure two large, thin metal plates are parallel and close to each other. On their inner faces, the plates have excess surface charge densities of opposite signs and magnitude 5.87 x 10-22 C/m. What is the magnitude of the electric field at points (a) to the left of the plates, (b) to the right of them, and (c) between them? (a) Number i ! Units N/C or V/m (b) Number i i Units N/C or V/m (c) Number 0.0000000000663 Units N/C or V/m
