WebMar 18, 2024 · To integrate over the disk, the θ coordinate will range from − π / 2 to π / 2, and the r coordinate can be shown to range from 0 to 2 a cos θ. (To see this, draw a diagram and do the trig.) The potential at the origin (on the rim) is φ = k e ∫ σ d A r where k e is the electric constant ( 1 / 4 π ϵ 0 in SI units; 1 in Gaussian units). WebApr 12, 2024 · 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. The two effects "cancel out" such that the resulting electric field is that of a single point charge. Note that d q = σ d A, and because we are preserving Q, as R shrinks, the charge on the disk will ...
