At each point on the surface of the cube shown in the figure the electric field is parallel to the y-axis. The length of each edge of the cube is 17.0 cm. On the right face of the cube the electric field is E→ = (1100.0 N/C)j^, and on the left face it is E′→ = (−2200.0 N/C)j^. Determine the net charge contained within the cube. C
