Charged disk electric field formula
WebElectric field due to a uniformly charged disc. E=kσ2π[1− z 2+R 2z] where k= 4πϵ 01 and σ is the surface charge density. WebApr 12, 2024 · The actual formula for the electric field should be E → = σ 2 ϵ [ x x − x ( x 2 + R 2) 1 / 2] ı ^, which you can see if you follow the derivation of the equation. Solution 2 I think the mystery comes from the fact that as R → you will find that σ, the area charge density, will become infinitely great.
