The equipotential planes in a particular region of space are shown in Figure P18.37. (a) What is the approximate magnitude and direction of the electric field at the origin? Consider only the components of the field along x and y. (b) Is the magnitude of the field larger at the origin or at the point (x, y) = (1.0 m, 1.0 m)?
