Вопрос школьника по предмету Физика
металлический шарик укрепленный на длинной изолирующий ручке и имеющий заряд +q приводят поочередно в соприкосновение с двумя такими же шариками 2 и 3 расположенными на изолирующий подставках и имеющими заряды соответственно -3q и +2q
Какой заряд останется на шарике 3
Ответ учителя по предмету Физика
Сначала первый шарик +q соприкасается с шариком -3q, их заряды распределятся равномерно (так как шарики одинаковые), то есть по -2q. Второе соприкосновение: шарик -2q соприкасается с третьим шариком
+2q, заряды также распределятся равномерно. Значит, в шарике 3 останется заряд = 0.
