Define electric flux and write its SI unit. Use Gauss's law to obtain the expression for the electric field due to a uniformly charged infinite plane sheet. A cube of side L is kept in space, as shown in the figure. An electric field E = (Ax + B) î N/C exists in the region. Find the net charge enclosed by the cube.
