Question

Дать точно определение электрического поля с формулой

Answer 1

Ответ:

Электрическое поле — одна из двух компонент электромагнитного поля, представляющая собой векторное поле, существующее вокруг тел или частиц, обладающих электрическим зарядом, а также возникающее при изменении магнитного поля (например, в электромагнитных волнах).

Здесь E – напряжённость электрического поля, F – сила, действующая на заряд, q – величина заряда.

Единица измерения напряжённости электрического поля – В/м (вольт на метр) или Н/Кл (ньютон на кулон).

Answer 2

Electric Field Definition and Formula

An electric field is a physical field that surrounds electrically charged particles and exerts a force on other charged particles within its vicinity. It is a fundamental concept in electromagnetism and is used to describe the behavior of electrically charged objects.

The electric field at a point in space is defined as the force experienced by a positive test charge placed at that point, divided by the magnitude of the test charge. Mathematically, it can be expressed as:

E = F/q

Where: - E represents the electric field strength at a given point, - F represents the force experienced by the test charge, - q represents the magnitude of the test charge.

The electric field is a vector quantity, meaning it has both magnitude and direction. The direction of the electric field is the direction in which a positive test charge would move if placed at that point.

It's important to note that the electric field is created by charged particles and is not affected by the presence of other charged particles. The electric field exists independently of the presence of other charges.
