The intensity of an electric field at a point can be derived from Coulomb's law, which states that the electric field between two charges is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them. Mathematically, the expression for electric field intensity (E) at a point is given by (E = \frac{k \cdot |q|}{r^2}), where (q) is the charge creating the field, (r) is the distance from the charge to the point, and (k) is the Coulomb's constant.

What is relation between electric field intensity and electric potential?
Electric field intensity is related to electric potential by the equation E = -∇V, where E is the electric field intensity and V is the electric potential. This means that the electric field points in the direction of steepest decrease of the electric potential. In other words, the electric field intensity is the negative gradient of the electric potential.
What factors determine the intensity of an electric field?
The intensity of an electric field is determined by the amount of charge creating the field and the distance from the charge. The closer you are to the charge, the stronger the electric field will be.
Is electric field intensity is an vectors?
Yes, electric field intensity is a vector quantity because it has both magnitude and direction. The direction of the electric field intensity indicates the direction of the force that a positive test charge would experience if placed in that field.
How can Gauss's law be utilized to determine an expression for the electric field strength within a slab?
Gauss's law can be used to find the electric field strength within a slab by considering a Gaussian surface that encloses the slab. By applying Gauss's law, which relates the electric flux through a closed surface to the charge enclosed by that surface, one can derive an expression for the electric field strength within the slab.
What is the electric field intensity at the mid point of dipole?
The electric field intensity at the midpoint of a dipole is zero. This is because the electric fields created by the positive and negative charges of the dipole cancel each other out at that point, resulting in a net electric field intensity of zero.

Electric field intensity is related to electric potential by the equation E = -dV/dx, where E is the electric field intensity, V is the electric potential, and x is the distance in the direction of the field. Essentially, the electric field points in the direction of decreasing potential, and the magnitude of the field is related to the rate at which the potential changes.

What represent the surface integral of electric field intensity?
Electric flux.
Is the electric intensity at any two points in a uniform electric field equal?
Yes, in a uniform electric field, the electric intensity is the same at any two points. This is because the electric field strength is constant in magnitude and direction throughout the entire region of the field.
What is the amplitude of the associated electric field?
The amplitude of the associated electric field refers to the maximum strength or intensity of the electric field. It represents the peak value of the electric field's magnitude.
Why is electric field intensity zero at the centre of an electric dipole?
At the center of an electric dipole, the electric field vectors from the positive and negative charges cancel each other out due to their opposite directions. This results in a net electric field intensity of zero at the center of the dipole.
Is electric field intensity a vector quanity?
Yes, it is.
How does electric field intensity form?
The electric field intensity is formed by the presence of electric charges. It is a vector quantity that represents the force experienced by a positive test charge per unit charge at a given point in space. The magnitude and direction of the electric field intensity depend on the distribution of charges in the vicinity.
