Coulomb’s Law
Electric charges have specific properties that say like charges repel each other whereas unlike charges attract each other. The magnitude of the force between the charges can be understood using Coulomb’s Law.
Coulomb’s Law says that,
“The magnitude of the electrostatic force between two point charges (either attraction or repulsion) is directly proportional to the product of the magnitudes of charges and is inversely proportional to the square of the distance between them.”
Coulomb’s Law is mathematically explained as,
F = kq1q2 / r2
where,
- k is Coulomb’s constant and its value is, 8.988×109 N⋅m2/C2
- r is distance between the charges

Electric Charge
Electric Charge is the basic property of a matter that causes the matter to experience a force when placed in a electromagnetic field. It is the amount of electric energy that is used for various purposes. Electric charges are categorized into two types, that are,
- Positive Charge
- Negative Charge
Positive and Negative charges have opposite properties. We have to study Electric Charge in classes 10 and 12. In this article, we will learn about electric charge, types of electric charge, methods of charging, properties of charge and others in detail.
