Здравствуйте, уважаемые коллеги.
Прошу Вашей помощи, не откажите, если сочтете возможным, пожалуйста.
С ребенком решаем задачи. Первую мы с ним решили. Прошу обратить внимание на вторую.
***
4) Рассчитать напряженность электрического поля бесконечной равномерно заряженной нити (плотность заряда λ) на расстоянии Н от нее.
5) Используя результат задачи 4, рассчитать электрическое поле бесконечной равномерно заряженной плоскости (плотность заряда σ), рассматривая ее как совокупность тонких бесконечных нитей.
***
Ответ в первой (4) задаче: E=[$955$]/(2*п*е0*Н)
А вот как подобраться к 5-й... ? Понятно, что нужно составить какой-то интеграл, но не хватает нам математической подготовки.
Порылся в интернете - есть решения, но вот как совокупность нитей плоскость нигде не рассматривают (не нашел, по крайней мере).
Благодарю
