Задача 30940.

There are two infinite parallel planes, charged with surface charge density + sigma and sigma. Initially they are in a vacuum. Then, the gap between the planes is filled with uniform isotropic dielectric permittivity e. Find what is going on at the same time with the potential difference between the planes.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.

If you have any questions to address, please. I´ll try to help.
