Practise 103 COMEDK previous year questions on Electrostatics, compiled from papers spanning 2012 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 COMEDK tests.

Electrostatics has been asked in 15 of the 15 years of COMEDK papers analysed (2012–2026), with 103 questions in all. 47% of them were easy, 46% moderate and 8% tough. Most of its questions came from 2024, with 21 questions that year. In the last three years (2024–2026) it had 53 questions across 10 papers, about 5.3 per paper.

The chapter's 5 topics are not weighted equally: Electric Charge and Coulomb's law (30 questions, 29%), Electric Field and Electric Field Lines (26 questions, 25%), and Electric Potential and Potential Energy (25 questions, 24%) have been asked the most. Over the last five years the most frequent topics have been Electric Field and Electric Field Lines (19), Electric Charge and Coulomb's law (17), and Electric Potential and Potential Energy (14). Electric Field and Electric Field Lines has produced the most tough questions (3).
