A slab of insulating material(infinite in both x and y directions )has
a charge density ρ.
The thickness(along z direction)of the slab is d.
Find the electric field E(向量) in both the exterior and interior
regions of the slab for the following the case:
1 ρ=ρv is a constant throughout the slab ,and
2 ρ=kz,where Co is a constant.
抱歉,我手边没相机, 第一次在这po文,希望神人大大可以为小弟解惑一下~
想了老半天,我一直想不透电场在0<z<d的答案算法
对了,这题是交大电物的,不知那一年的。麻烦各位了
