3. Как будут взаимодействовать заряды, показанные на рисунке 44, — притягиваться или отталкиваться?
Рис. 44. К вопросу 3
Решение. №3 (с. 65)
Решение
Для определения характера взаимодействия зарядов необходимо использовать основной принцип электростатики: заряды с одинаковыми знаками (одноименные) отталкиваются, а заряды с противоположными знаками (разноименные) притягиваются.
Рассмотрим каждую из четырех пар зарядов, представленных на рисунке:
Верхняя левая пара
На рисунке показаны положительный (+) и отрицательный (–) заряды. Так как знаки зарядов противоположны, они являются разноименными и будут притягиваться друг к другу.
Ответ: притягиваться.
Нижняя левая пара
На рисунке показаны отрицательный (–) и положительный (+) заряды. Эти заряды также являются разноименными, поэтому между ними будет действовать сила притяжения.
Ответ: притягиваться.
Верхняя правая пара
На рисунке показаны два положительных (+) заряда. Так как знаки зарядов одинаковы, они являются одноименными и будут отталкиваться друг от друга.
Ответ: отталкиваться.
Нижняя правая пара
На рисунке показаны два отрицательных (–) заряда. Эти заряды также являются одноименными, следовательно, между ними будет действовать сила отталкивания.
Ответ: отталкиваться.
