Question

5.Два одинаковых металлических шара, заряженных одинаковыми по значению и противоположными по знаку зарядами, после соприкосновения оказались электрически нейтральными. Можно ли сказать, что заряды в шарах исчезли? Объясните почему.

Answer 1

носителями заряда в этом случае являются электроны.

На одном шаре их избыток - он заряжен отрицательно.

На другом их недостаток - он заряжен положительно.

После соприкосновения электроны распределятся равномерно по двум шарам и они станут электрически нейтральны. Но заряды не исчезают.

Answer 2

Answer:

No, the charges in the spheres did not disappear.

When two identical metal spheres with equal and opposite charges come into contact and then separate, the charges redistribute themselves on the spheres. This redistribution results in the spheres being electrically neutral, but the charges themselves do not disappear. The excess charge from one sphere is transferred to the other, resulting in both spheres having the same amount of charge but with opposite signs. This process is known as charge conservation.

This phenomenon can be explained by the principle of charge conservation, which states that the total electric charge in an isolated system remains constant over time. Therefore, the charges in the spheres did not disappear; they simply redistributed themselves to achieve electrical neutrality.

The redistribution of charges is a result of the principle of charge conservation, which is a fundamental concept in physics and is supported by experimental evidence and theoretical models.
