Gauss Law
In a cubical volume of side length a = 0.50 m, the electric field is Ē = E(1 + 2.5²) + Eo(1+2.2)ĵ, where E = 0.15 N/C. The cube has its sides parallel to the coordinate axes as shown in the figure. Determine the net charge within the cube in units of picocoulomb (1pC= 10-12 C). (Take co Answer: = 8.85 x 10-¹2 C2/(Nm²).)
