Coulomb’s law Problems and Applications

Coulomb’s Law Coulomb’s law enables us to calculate the electrostatic force between any two point charges. It holds for distances ranging from 10-15 to 1018 m. The force of interaction between any two point charges is directly proportional to the product of the electrical charges and inversely proportional to the square of the distance between them. … Read moreCoulomb’s law Problems and Applications

Electrical Charges and its Properties

Electrical Charges (q) Electrical charges are the intrinsic property of the elementary particles of matter which give rise to an electric force between various objects.It is a scalar quantity.
