Направление сил указано верно. <strong>Ответ:</strong> ошибки нет.</p><p><strong>в)</strong> На рисунке показано взаимодействие отрицательного (−) и положительного (+) зарядов. Как и в случае (а), это разноименные заряды, и они должны притягиваться. На рисунке ошибочно показано отталкивание. <strong>Ответ:</strong> ошибка, разноименные заряды притягиваются.</p><p><strong>г)</strong> На рисунке показано взаимодействие двух отрицательных (−) зарядов. Это одноименные заряды, поэтому они должны отталкиваться друг от друга. Направление сил на рисунке указано верно. <strong>Ответ:</strong> ошибки нет.</p><p><strong>д)</strong> На рисунке показано взаимодействие нейтрального (незаряженного) тела и положительно заряженного (+). Вследствие явления электростатической индукции, заряженное тело всегда притягивает нейтральное. На рисунке ошибочно показано отталкивание. <strong>Ответ:</strong> ошибка, заряженное тело притягивает нейтральное.</p>" ] #changes: [] #casts: [] #classCastCache: [] #attributeCastCache: []

№1 (с. 102)
Условие. №1 (с. 102)
скриншот условия
1. На рисунке 56 показано взаимодействие заряженных тел. Найдите ошибки в рисунке и исправьте их.
Решение 1. №1 (с. 102)
Решение 2. №1 (с. 102)
Решение 3. №1 (с. 102)
Решение 4. №1 (с. 102)
Решение
Для анализа каждого случая, представленного на рисунке, необходимо применить основные законы электростатики: тела с одноименными зарядами отталкиваются, тела с разноименными зарядами притягиваются, а заряженное тело притягивает незаряженное (нейтральное) тело.
а) На рисунке показано взаимодействие положительного (+) и отрицательного (−) зарядов. Согласно закону электростатики, разноименные заряды должны притягиваться. На рисунке же изображено их отталкивание, что является ошибкой. Правильно было бы направить стрелки сил навстречу друг другу. Ответ: ошибка, разноименные заряды притягиваются.
б) На рисунке показано взаимодействие двух положительных (+) зарядов. Одноименные заряды отталкиваются, что и показано на рисунке. Направление сил указано верно. Ответ: ошибки нет.
в) На рисунке показано взаимодействие отрицательного (−) и положительного (+) зарядов. Как и в случае (а), это разноименные заряды, и они должны притягиваться. На рисунке ошибочно показано отталкивание. Ответ: ошибка, разноименные заряды притягиваются.
г) На рисунке показано взаимодействие двух отрицательных (−) зарядов. Это одноименные заряды, поэтому они должны отталкиваться друг от друга. Направление сил на рисунке указано верно. Ответ: ошибки нет.
д) На рисунке показано взаимодействие нейтрального (незаряженного) тела и положительно заряженного (+). Вследствие явления электростатической индукции, заряженное тело всегда притягивает нейтральное. На рисунке ошибочно показано отталкивание. Ответ: ошибка, заряженное тело притягивает нейтральное.
