E field in sphere

WebSep 16, 2024 · The only way for a vector field to have strict spherical symmetry is for it to be purely in the radial direction. For, if it had a non-radial component then that component would have to be preserved under rotations, but you cannot construct a vector field which has that property everywhere on the surface of a sphere. I provide a proof below. WebSep 12, 2024 · At any point just above the surface of a conductor, the surface charge density δ and the magnitude of the electric field E are related by. (6.5.3) E = σ ϵ 0. To see this, consider an infinitesimally small Gaussian cylinder that surrounds a point on the surface of the conductor, as in Figure 6.5. 6.
