Zero Total Charge: How is this Possible?

Click For Summary
SUMMARY

The discussion centers on the phenomenon of having a non-zero electric field (E), non-zero electric flux density (D), and non-zero volumic charge density (ρV) while integrating volumic charge density (ρV) over a specified region results in zero total charge. This scenario challenges conventional understanding of charge distribution and suggests that local charge densities can exist without contributing to a net charge, possibly due to the presence of bound charges or polarization effects in the medium. The integration of volumic charge density yielding zero indicates a balance of positive and negative charges within the region.

For a certain problem I have non-zero electrical field E, non-zero electric flux density D, and non-zero volumic charge density ρV.

When I integrate pV dV over the given region, I get 0.

How is this possible?

Why do you think it's not possible to have zero net charge in such a region?
