Hello everyone. I'm having problems figuring out this check point. I have attached an image that has the diagram. Incase you can't read the picture it says: The figure shows two large, parallel, noconducting sheets with identical positive uniform surface charge densities, and a sphere with a uniform (positive) volume charge density. Rank the four numbered points according to the magnitude of the net electric field there, greatest first. The answers are: 3 and 4 tie, then 2, 1. Why would 3 and 4 be the greatest? I'm confused! Do the two non conducting plates not play a role in this problem because they are equal?
