Chapter 23, Problem 36P

Figure 23-47 shows cross sections through two large, parallel, nonconducting sheets with identical distributions of positive charge with surface charge density σ = 1.77 × 10⁻²² C/m². In unit-vector notation, what is $\stackrel{\to }{E}$ at points (a) above the sheets, (b) between them, and (c) below them?
