Question

Write the expression for the electric field in the regions $I, I I, I I I$ shown in figure

Open in App

Solution

As both $E_{+} = E_{-} = \frac{σ}{2 ε_{0}}$
Hence net electric field in region 1 = $0$
Net electric field in region 2 = $\frac{σ}{2 ε_{0}} + \frac{σ}{2 ε_{0}} = \frac{σ}{ε_{0}}$
And similarly, net electric field in region 3 = $0$
