Electro Statistics
Electrostatics is a branch of physics that deals with the study of electric charges at rest and the forces and fields associated with them. In the context of the NEET (National Eligibility cum Entrance Test) chemistry syllabus, electrostatics is an important topic that you need to understand. Here is a crash course on the electrostatics portion of the NEET chemistry syllabus:
- Electric Charge: The concept of electric charge is fundamental to electrostatics. There are two types of charges: positive (+) and negative (-). Like charges repel each other, while unlike charges attract each other.
- Coulomb’s Law: Coulomb’s law describes the electrostatic force between two point charges. It states that the force between two charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the distance between them. The formula for Coulomb’s law is F = k(q₁q₂)/r², where F is the force, q₁ and q₂ are the charges, r is the distance between them, and k is the electrostatic constant.
- Electric Field: An electric field is a region around a charged object in which another charged object experiences a force. The electric field is a vector quantity and is defined as the force per unit charge. The formula for electric field intensity (E) is E = F/q, where E is the electric field, F is the force, and q is the test charge.
- Electric Potential: Electric potential is the electric potential energy per unit charge at a point in an electric field. It is a scalar quantity and is measured in volts (V). The electric potential difference between two points is given by ΔV = W/q, where ΔV is the potential difference, W is the work done, and q is the charge.
- Capacitance: Capacitance is a measure of an object’s ability to store electric charge. It is defined as the ratio of the magnitude of the charge on one plate to the potential difference between the plates. The formula for capacitance is C = Q/V, where C is the capacitance, Q is the charge, and V is the potential difference.
- Dielectrics: Dielectrics are insulating materials that are placed between the plates of a capacitor to increase its capacitance. Dielectrics reduce the electric field between the plates and store additional charge. The presence of a dielectric material increases the capacitance of a capacitor by a factor called the dielectric constant (K).
- Gauss’s Law: Gauss’s law relates the electric flux through a closed surface to the charge enclosed by that surface. Mathematically, it states that the electric flux (Φ) through a closed surface is equal to the total charge (Q) enclosed by that surface divided by the permittivity of free space (ε₀). The formula for Gauss’s law is Φ = Q/ε₀.
- Electric Potential Energy: Electric potential energy is the energy possessed by a charged object due to its position in an electric field. The formula for electric potential energy is U = qV, where U is the potential energy, q is the charge, and V is the potential difference.
- Conductors and Insulators: Conductors are materials that allow the easy flow of electric charges, while insulators are materials that do not allow the flow of electric charges easily.
- Electrostatic Induction: Electrostatic induction is the process of creating a charge imbalance in an object by bringing a charged object near it without direct contact. This process is commonly used in various devices and applications.
These are some of the key concepts and topics you should focus on when studying electrostatics for the NEET chemistry syllabus. Make sure to practice numerical problems and understand the underlying principles to master this topic.

Case Study on NEET CHEMISTRY SYLLABUS Electro Statistics
Van de Graaff Generator
Introduction: A Van de Graaff generator is a device that uses electrostatics to generate high voltages. It is commonly used in laboratories and educational settings to demonstrate electrostatic phenomena and conduct experiments. Let’s explore the working principle of a Van de Graaff generator and its applications.
Background: The Van de Graaff generator was invented by physicist Robert J. Van de Graaff in the 1920s. It consists of a large metal sphere mounted on top of an insulating column. Inside the column, there is a motor-driven belt made of insulating material, such as rubber or nylon. Two pulleys are used to move the belt continuously.
Working Principle: The working principle of a Van de Graaff generator involves three main processes:
- Charge Separation: Initially, the metal sphere of the generator is uncharged. As the belt moves, it rubs against another material, such as a comb or brush, causing electrons to be transferred from the belt to the comb/brush. This creates a positive charge on the comb/brush and a negative charge on the belt.
- Charge Accumulation: The positive charges on the comb/brush are then transferred to the metal sphere. Due to the repulsion between like charges, the positive charges spread out on the outer surface of the sphere.
- Charge Transfer: The excess negative charges on the belt are carried upward and deposited onto a metal dome (called the discharge electrode). The negative charges repel each other and accumulate on the dome’s surface.
Applications: The Van de Graaff generator has various applications in physics and educational demonstrations, including:
- Electrostatic Experiments: The generator is used to create high voltage and charge conditions to conduct experiments on electrostatics. It can generate voltages in the range of thousands to millions of volts.
- Particle Acceleration: Van de Graaff generators are used in particle accelerators to accelerate charged particles, such as protons or electrons, to high energies for various research purposes.
- Electrostatic Precipitators: In industries, Van de Graaff generators are employed in electrostatic precipitators to remove dust particles from gases. The high voltage produced by the generator attracts and collects the charged dust particles, allowing cleaner gas to be released.
- Nuclear Physics: Van de Graaff generators are used in nuclear physics experiments to accelerate ions for nuclear research and study atomic and subatomic particles’ behavior.
Conclusion: The Van de Graaff generator is a fascinating device that utilizes the principles of electrostatics to generate high voltages. It has numerous applications in scientific research, education, and industrial processes. Understanding the working principle of the Van de Graaff generator provides insights into the fascinating world of electrostatics and its practical implications in various fields.
