2 infinite boards placed in space in x =5 and x = -5, charged with unformed positive density [tex]\sigma[/tex] , between those boards is a spacial distribution of charge [tex]\rho[/tex] given: [tex]\rho[/tex](x,y,z)=Ax^2 , A const. There is no charge outside the boards. I need to calculate the charge in a box with a side=4, located in (0,0,0) parallel to axis. I want to approach it using gauss. For this I need to find the flom through the box. My first question: Does the fields generated by the boards effect the box or they negate each other and only the spacial field effects?
