This law describe the electrostatic interaction between two charged bodies .. It is analogous to inverse-square law of universal gravitation . This is also known as inverse square law .

#### according to this law - the force between two charge particles is directly proportional to the multiplication of these two charges and inversely proportional to the square of distance separating these two charges .

Coulomb's law can also be stated as a simple mathematical expression. The scalar and vector forms of the mathematical equation are- and respectively,
