## Electric field intensity due to a point charge :

Let us calculate the electric field intensity due to a point P due to a point charge Q at O, where OP=r . If a small positive test charge be placed at P then following Coulomb’s law, the force acting on at P, where is a unit vector directed from Q to . So, electric …

## Principle of Superposition (Forces Among Multiple Charges and Continuous Charge Distribution):

The principle of superposition is used to calculate the force on a charge due to several stationary charges. The superposition principle states that, total force on any charge due to a number of other charges at rest is the vector sum of all the forces on that charge due to other charges, taken one at …

## Permittivity and Dielectric constant

We have mentioned about permittivity of free space and air but different medium have different absolute permittivities (E) and the Coulomb force F in the medium is given by, Whne they are placed in vaccum, Dividing , or, or, Where E is called relative permittivity of the medium or also called dielectric constant of the …

## Coulomb’s law: Force between two point charges

French scientist Charles Coulomb first gave the empirical law regarding the force between two point charges and is known as Coulomb’s law. The law states that-The force between two point charges at rest is directly proportional to the product of the magnitude of the charges and inversely proportional to the square of the distance between …
