Бывает, что при прикосновении к металлическому объекту, например, к дверной ручке, мы чувствуем неприятный укус, связанный с электрическим зарядом, протекающим между нашим телом и металлическим предметом. Это отчетливо ощущается, когда текущий заряд составляет около 600 нКл. Подсчитайте, сколько электронов проходит между вашей рукой и металлическим предметом.
*35 баллов. Помогите пожалуйста срочно!!!!

q = 600 нКл = 6*10² * 10⁻⁹ Кл = 6 *10⁻⁷ Кл

1 e = 1,602 *10⁻¹⁹ Кл

Ищем: e

оформляем пропорции:

1 e = 1,602 *10⁻¹⁹ Кл

xe = 6 *10⁻⁷ C

x =  1 e * 6*10⁻⁷Кл / 1,602 *10⁻¹⁹ Кл = 3,75 *10¹² e

Объяснение:

Дано:

q = 600 нКл = 600·10⁻⁹ Кл

e = 1,6·10⁻¹⁹ Кл - модуль заряда электрона

________________

N - ?

Число электронов:

N = q / e = 600·10⁻⁹ / (1,6·10⁻¹⁹ ) ≈ 3,8·10¹²
