WebThe last job we have is to find how much charge ( Q) is inside our surface. The charge density is σ = q 2 π r h There are two cases. If R > r, then the Q = 2 π r L σ = q L h. If R < r, then no charge is inside our surface, so Q = 0. So, using our final version of Gauss's law: E 2 π R L = Q ϵ 0 E = Q 2 π ϵ 0 R L And our final answer is: R < r; WebThe surface charge density on a solid is defined as the total amount of charge q per unit area A, \sigma = {q\over A}. The surface charge on a surface S with surface charge …
WebThen we take a disc with radius r and let’s choose this disc with a surface charge density of minus Sigma Coulombs per meter squared. That disc will generate an electric field along its axis z distance away from its center.
