Discussion Question 3C P212, Week 3 Electric Field due to Charged Sheets and Slabs You calculated the electric field of a charged plane of infinite area. The field turned out to be independent of distance. This property makes it easy to analyze systems of many charged sheets and slabs using superposition . Here’s a warmup exercise: consider the thick slab of infinite area shown at right. The slab is made of a non-conducting material. It carries a net charge per unit area of σ , which is distributed uniformly throughout the interior of the slab. (a) Write down the electric field E at the point x . E = σ /2 ε o (b) Would the field change if the slab were moved further to the left ? no (c) Would the field change if the thickness of the slab were increased slightly? no (d) Would the field change if the slab were replaced by two slabs , each carrying charge density σ /2? no See how easy superposition is with infinite planes? Let’s also remind ourselves how to deal with conductors .
