Electrostatics Key Points for JEE Main 2026

It is very important to go through the key points for the electrostatics chapter for the JEE Main 2026. Checking the key points will help the aspirants understand the concepts that are important for the electrostatics chapter. The key points for electrostatics comprise topics like Coulomb’s law, Electric Charge, Electric Field, and more. Check the Key points for electrostatics below:

Coulomb’s Law

The force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges.

• Coulomb’s First Law: Coulomb’s first law states that two charged particles of the same charge (positive or negative) will repel each other and two charged particles of opposite charges (one positive and one negative) will attract each other
• Coulomb’s Second Law: Coulomb’s second law states that the force of attraction or repulsion between two electrically charged particles is directly proportional to the product of magnitudes of two charges and inversely proportional to the square of the distance between two charges.

The Coulomb's law can be mathematically stated as

Where,

F = Force of attraction or repulsion between the charges

Q1, Q2= = magnitude of charge 1 and charge 2

d = Distance between two charges.

k = Constant whose value depends on the medium in which charges are placed.

Electric Charge: Conservation of Charge

Electric charge (symbol q, sometimes Q) is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. Electric charge can be positive or negative. Like charges repel each other, and unlike charges attract each other. An object with no net charge is referred to as electrically neutral. Early knowledge of how charged substances interact is now called classical electrodynamics and is still accurate for problems that do not require consideration of quantum effects.

• S.I unit of charge is Coulomb (q)
• Positive Charge and Negative Charge

Electric Field Due to Continuous Charge Distribution

When the charge is distributed uniformly over a conductor, it is known as a continuous charge distribution. In a continuous charge distribution, an infinite number of charges are closely packed together so that there is no space left between them. As a result, the load distribution is uninterrupted and flows continuously throughout the charging system, unlike the discrete charging system.

Three types of continuous charge distribution systems occur:

• Linear charge distribution
• Surface charge distribution
• Volume charge distribution

Gauss Law

The flux of the electric field out of an arbitrary closed surface is proportional to the electric charge enclosed by the surface, irrespective of how that charge is distributed. Even though the law alone is insufficient to determine the electric field across a surface enclosing any charge distribution, this may be possible in cases where symmetry mandates uniformity of the field. Where no such symmetry exists, Gauss's law can be used in its differential form, which states that the divergence of the electric field is proportional to the local density of charge.
