Electric potential of a disk
WebThe exact solution is E(R < r, θ = π / 2) = Q 4πϵ0( 1 r2) ∞ ∑ l = 0 (2l)! 22l(l!)2(R r)2lˆr. Clearly the field inside the conductor (that is, for r < R) vanishes. Here Q is the total charge on the disk. The field, for large values of r, looks essentially like a point charge (due to the fact that the series tapers off rather quickly ...
