This PDF is a question-heavy practice module on Electrostatics, covering Exercises 1 to 3. It is designed mainly for competitive exam preparation and focuses on strengthening problem-solving skills rather than theory. The questions are presented in multiple-choice format and span all core areas of Electrostatics, including electric charge, Coulomb’s law, electric field, electric potential, energy, dipoles, Gauss’s law, and conductors.
I am writing about this PDF because many students read theory but struggle when it comes to applying concepts in numerical and conceptual MCQs. This document clearly shows the type, depth, and pattern of questions students are expected to handle in exams. Understanding what is included here helps learners practise smarter and revise more effectively.
Structure of the Exercises
The PDF is divided into clearly labelled sections, each focusing on a specific Electrostatics concept. Every section contains multiple MCQs with one correct option, closely aligned with exam standards. The progression of questions moves from basic understanding to application-based and analytical thinking.
The exercises are cumulative, meaning earlier concepts like charge and force are repeatedly used in later sections such as potential energy and Gauss’s law.
Properties of Electric Charge and Coulomb’s Law
The first section tests understanding of charge quantisation, conservation of charge, dielectric constant, and Coulomb’s law. Questions involve force comparison, charge redistribution between conducting spheres, effect of medium, and analogy between electrostatic and gravitational forces.
Several problems test symmetry, equilibrium of charges, and the effect of introducing additional charges near existing ones.
Electric Field Concepts
A large portion of the PDF focuses on electric field intensity. Questions include direction of force on charged particles, field due to point charges, infinite line charges, charged sheets, spherical shells, and solid spheres.
There are multiple problems based on electric field inside and outside conductors, maximum field conditions, and force on charges placed between or outside parallel plates.
Electric Potential and Potential Difference
This section contains questions that relate potential to electric field and distance. Problems include potential due to point charges, rings, discs, spherical shells, and systems of charges.
Several MCQs test conceptual clarity, such as situations where electric field is zero but potential is not zero, and vice versa. Numerical problems involve electron volt, kinetic energy gain, and potential variation graphs.

Electric Potential Energy
The PDF includes a dedicated section on electric potential energy of a particle and of a system of charges. Questions test work done in moving charges along different paths, energy changes in electric fields, and motion of charged particles under electrostatic forces.
Problems also involve closest distance of approach, speed after acceleration through potential difference, and conservation of energy principles.
Dipole-Based Questions
Electric dipole concepts are tested thoroughly. Questions include torque on a dipole, potential and field on axial and equatorial positions, dipole moment calculations, and energy of dipole in uniform and non-uniform fields.
The exercises also test understanding of direction and magnitude of force and torque acting on dipoles placed at different orientations.
Gauss’s Law and Electric Flux
This section focuses on electric flux calculations and applications of Gauss’s law. Questions involve closed surfaces, cubes, spheres, cylinders, and hemispherical shells.
Several MCQs test whether flux depends on position of charge inside a surface and how flux behaves when charges are moved within a Gaussian surface.
Conductors and Electrostatic Properties
The PDF includes questions on charge distribution in conductors, electric field inside conductors, surface charge density, electric pressure, and behaviour of conductors in external electric fields.
Problems also include shielding effect, induced charges, potential distribution, and force between conductors after contact.
Exam-Oriented Nature of the PDF
All questions are strictly MCQ-based and framed to test speed, accuracy, and conceptual clarity. Many questions require elimination of options rather than direct calculation, which reflects real competitive exam conditions.
The repetition of concepts across sections reinforces learning and exposes students to different ways the same idea can be tested.
