The figure shows a closed Gaussian surface in the shape of a cube of edge length 2.30 m. It lies in a region where the electric field is given by E = (4.33x + 5.10)i + 6.07 j + 5.23 k N/C, with x in meters. What is the net charge contained by the cube?Flux and nonconducting shells. A charged particle is suspended at the center of two concentric spherical shells that are very thin and made of nonconducting material. Figure (0) shows a cross section. Figure (b) gives the net ux
