PBS趣味科普 It actually has infinite planes of symmetry rotating around its center here. 它实际上有无限的对称平面围绕着它的中心旋转。 玩转物理学 What if we add an equal magnitude, parallel, infinite plane of negative charges? 如果我们添加一个等量、平行、无限的负电荷平面会怎样? 玩转物理学 First off, we know the electric field will be normal to and directed away from the infinite plane of positive charges. 首先,我们知道电场垂直于正电荷的无限大平面,并远离正电荷的无限大平面。 玩转物理学 Basically, we have an infinitely large, infinitesimally thin, two-dimensional plane of positive charges which are evenly spread out through the infinite plane. 基本上,我们有一个无限大、无限薄的二维正电荷平面,这些正电荷均匀分布在无限平面上。 玩转物理学 Oh, and realize, the surface charge density in the equation now refers to the magnitude of the surface charge density, which is the same for both infinite planes of charges. 哦, 请注意, 等式中的表面电荷密度现在指的是表面电荷密度的大小,对于两个无限大的电荷平面来说都是相同的。 |
