Coulomb's law is a fundamental law of physics that describes the force between two electrically charged particles. It states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
In order to represent the force between two charged particles, we can use a vector to show the direction and magnitude of the force. The direction of the vector will be in the direction of the force, and the length of the vector will be proportional to the magnitude of the force.
No, Coulomb's law can be applied to any two charged objects, regardless of their size or shape. However, it is more accurate for point charges, which are objects with negligible size compared to the distance between them.
According to Coulomb's law, as the distance between two charged particles increases, the force between them decreases. This is because the force is inversely proportional to the square of the distance between the particles. So, the farther apart they are, the weaker the force between them.
Yes, in addition to the distance between the particles, the magnitude of the charges and the medium between them can also affect the force. For example, if the particles are in a medium with a high dielectric constant, the force between them will be weaker compared to if they were in a medium with a lower dielectric constant.
