Coulomb"s Law :
This law states that the force of attraction or repulsion between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Electric Field :
The electric field due to a charge is the space around the test charge in which it experiences a force.
The presence of an electric field around a charge cannot be detected unless another charge is brought towards it.
Electric field Intensity :
The electric field intensity at a point in an electric field is defined as the force experienced by a unit positive charge kept at that point
It is a vector quantity.
It can also be referred as Electric field strength or simply electric field
