## Summary:

- Doubt about the 1st Law of Maxwell, concerning the E field created by a disk

## Main Question or Discussion Point

Good afternoon,

My question concerns Maxwell's first law. Knowing the formula of the electric field created by a uniformly charged disk, we calculate its divergence and evaluate it at one point, it does not give us zero, as it should be because the volumetric density of charge is zero, why does this happen? Where is the error in my reasoning?
