It is defined as the number of electric field lines associated with an area element.Therefore, total flux through the faces of the given cube = q/2ϵ 0.
If the charge q is placed at C, the center of a face of the cube, it is being shared equally by 2 cubes.If A point charge q is placed at a distance x/2 directly above the center of a cube of side x, it will be at the face of the cube.The magnitude of flux ϕ = Q / ϵ 0 (if the charge is placed at the center of the cube).According to this law, the total charge Q enclosed in a closed surface is proportional to the total flux ϕ enclosed by the surface.Gauss' Law: This law gives the relation between the distribution of electric charge and the resulting electric field.Where ϕ is the flux, E is the electric field, and dA is the small area. The electric flux through a chosen surface is given by: common interests and common objectives are not necessary for society.Electric flux (ϕ): The number of electric field lines passing through a surface area normally is called electric flux.It is a network of social relationships which cannot see or touched.There can be more than one community in a society.
The dielectric constant or relative permittivity of a medium can be defined as the ratio of the permittivity of a medium and the permittivity of vacuum of free space. The dipole moment exists only when the positive and negative centres are separate.Ĭoloumb's law states that "the force of attraction or repulsion between two charges is directly proportional to the product of charges and inversely proportional to the square of the distance between them."
The dipole moment of an isolated atom is zero because the centre of positive and negative charge coincides. The dipole moment of an electric dipole is defined as the product of the two equal charges and perpendicular distance between them i.e. Two equal and opposite charges separated at certain finite distance constitutes electric dipole. Hence, electric lines flux can be defined as the scalar product of electric flux intensity and vector area. system and charges present in the air or Vaccum Here, K is the proportionality constant whose value depends upon the medium in which charges are present and the system of a unit chosen.įor S.I. It states that "the force of attraction or repulsion between two charges is directly proportional to the product of charges and inversely proportional to the square of the distance between them."įigure: Two charges separated by a distance r apart. Electric Field Intensity and Electric Flux Coloumb's LawĬoloumb's Law is applied to calculate the force of attraction or repulsion between two-point charges.
