Задача 31414.

Endlessly long straight thin rod charged uniformly throughout the length of the linear charge density of 1 l / m. Find the potential difference of the two points of the field, remote from the rod at a distance of 0.5 m and 2 m, and the work of moving the probe 5 mC charge from one point to another.

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