The long cylinder of radius 0.5 m filled with uniform isotropic dielectric with permittivity 4 and a bulk density of charge -2 x 10 -4 C / m ^ 3. To determine the potential difference of the points A and B, at distances of 0.1 m and 0.25 m from the axis of the cylinder.
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.
