Physics - Electrostatics

Practise 53 WBJEE previous year questions on Electrostatics, compiled from papers spanning 2009 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty WBJEE tests.

Electrostatics has been asked in 18 of the 18 years of WBJEE papers analysed (2009–2026), with 53 questions in all. 34% of them were easy, 43% moderate and 23% tough. Most of its questions came from 2022, with 6 questions that year. In the last three years (2024–2026) it had 6 questions across 3 papers, about 2 per paper.

The chapter's 5 topics are not weighted equally: Electric Potential and Potential Energy (15 questions, 28%), Electric Field and Electric Field Lines (15 questions, 28%), and Electric Charge and Coulomb's law (10 questions, 19%) have been asked the most. Electric Potential and Potential Energy has also led over the last five years, with 5 questions. Electric Field and Electric Field Lines has produced the most tough questions (3).
