Electric Force between Two Points Charges (Coulomb’s Law of Electrostatic Force)

Like charges repel and unlike charges attract. Based on this, Coulomb’s law of electrostatic force came into being. The law states that, ‘The electrostatic force of attraction or repulsion Fbetween two point charges is directly proportional to the product of the charges and inversely proportional to the square of their distance apart.’



Where k=14πϵ0

Hence, FC=Q1Q24πϵ0r2

Where ϵ0=8.85×10−12F/m

and k=9×109Nm2/C2
