Решение задачи по физике раздел 68 пункт 19 электро

19. The electrostatic field is created by an infinite uniformly charged plane with a surface density of σ = 10 nC / m2. Determine what speed the electron will gain under the influence of external forces, approaching along the line of tension from a distance r1 = 2 cm to a distance r2 = 1 cm from the filament.
