The fundamental relationship between the resulting electric field and electric charge distribution is given by Gauss's law.
It states that the total electric flux (? E) passing through any closed hypothetical surface (called a Gaussian surface) is equal to 1/?0 times the net electric charge (q enc ) enclosed within that surface.
When dealing with charge distributions that possess a high degree of symmetry such as planar, cylindrical, and spherical, Gauss's law significance lies in providing a powerful alternative method to Coulomb's law for calculating electric fields.

A region around a charged object, where another object experiences a force is called an electric field. The formula is - E = F / q? where E is the electric field at a point, q? is the small positive test charge placed at that point, and F is the force experienced by q?
The electric field is a vector quantity that has both magnitude and direction. The electric fields are visually represented by the electric field lines. The electric field starts with positive charges and ends with negative charges. The field's strength is indicated by the density of the field lines. The electric fields can be measured in V/m (volts per meter) and N/C (n

According to Shiksha's electric charges and fields class 12 notes, Coulomb's law states that if there are two stationary point charges, the electrostatic force between them is inversely proportional to the square of the distance between them and directly proportional to the product of the charges.
Mathematically,
F = (1 / 4? ) * (q? / r²)
Here r is the distance between the charges, q? and q? are charges and? is the permittivity of free space. Coulomb's law assumes charges are at rest and it is valid for point charges in vacuum or air. When the medium is not a vacuum and the charges are moving, the limitations include inaccuracy. This la

The quantization of charge can be denoted as e = 1.6 * 10? ¹? C. It means that the object's charge is an integral multiple of the elementary charge. Mathematically, it can be represented as q = ±ne, where n is an integer. The charge exists in discrete packets or quanta and is not continuous. For example, a body cannot have a charge of 2.5e but a charge of 3e or -2e. Millikan first observed this quantization of charge in his oil drop experiment. Quantization is consistent with the matter's atomic structure and is a fundamental property of electric charge.
