Coulomb's Law

#. COULOMB'S LAW : 

It states that the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two objects. 

                 

NOTE : 

Coulomb's Law is valid only for point charges. It means distance between the charges must be larger than its size.

• When there is similar charges, then the force is less than Coulomb force.

   But, when there is opposite charges, then the force is more than Coulomb force .

#. Principle of Superposition of Electrostatic Forces : This principle states that the net electric force experienced by a given charge particle q₀ due to a system of charged particles is equal to the vector sum of the forces exerted on it due to all the other charged particles of the system.
