Electric charges are the fundamental source of electric fields, which are used to describe the force that charges experience in a particular environment. Electric fields are vector fields that surround a charged object and describe the force that would be experienced by another charged object placed in that environment. The strength of an electric field is proportional to the amount of electric charge producing it, and decreases with distance from the charge. The direction of the electric field is defined as the direction of the force that a positive test charge would experience if placed in that field. The interaction between electric charges and electric fields is governed by Coulomb's law, which states that the force between two point charges is proportional to the product of the charges and decreases with the square of the distance between them. Electric fields and charges are fundamental concepts in physics, and play a crucial role in many areas of science and technology, incl
