Coulomb’s Law

Coulomb’s Law

The magnitude of the force between the two electric charges is variable according to the size of each charge and is inversely proportional to the square of the distance between the two charges. The direction of the forces acting on each other is in a straight line connecting the pairs of charges. The force acting between the charges of the same type (both positive or both negative) is repulsive and points apart in a straight line connecting the two charges The force acting between different charges (positive and negative) is an attraction. and have direction pointing towards each other in a straight line connecting the two charges.

Coulomb (Charles-Augustin de Coulomb) French physicist Born June 14, 1736, he is widely known as the discoverer of the so-called fundamental laws of electromagnetism. Coulomb’s law, which describes the magnitude of attraction and repulsion between electric charges.

Did you know? Coulomb (C) was named in honor of the unit of “electric charge” in the SI system. Charles-Augustin de Coulomb , where 1 C is equal to the amount of electric charge from a current of 1 A moving in 1 s.

Formula:
F = k frac{q_1q_2}{r^2}
F = electric force
k = Coulomb constant
q_1, q_2 = charges
r = distance of separation

What is Coulomb’s law?

According to Coulomb, the electric force for charges at rest has the following properties: Like charges repel each other; unlike charges attract. Thus, two negative charges repel one another, while a positive charge attracts a negative charge. The attraction or repulsion acts along the line between the two charges.

Coulomb’s law states that: “The magnitude of the Electrostatics force of interaction between two point charges is directly proportional to the scalar multiplication of the magnitudes of charges and inversely proportional to the square of the distances between them.”
