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,我手邊沒相機, 第一次在這po文,希望神人大大可以為小弟解惑一下~
想了老半天,我一直想不透電場在0<z<d的答案算法
對了,這題是交大電物的,不知那一年的。麻煩各位了
