Physics - Mathematics in Physics
Practise 25 WBJEE previous year questions on Mathematics in Physics, 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.
Mathematics in Physics has been asked in 16 of the 18 years of WBJEE papers analysed (2009–2026), with 25 questions in all. 60% of them were easy, 36% moderate and 4% tough. Most of its questions came from 2010, with 3 questions that year. In the last three years (2024–2026) it had 5 questions across 3 papers, about 1.7 per paper.
The chapter's 4 topics are not weighted equally: Addition and Subtraction of Vectors (9 questions, 36%), Errors of Measurement (6 questions, 24%), and Multiplication of Vectors (6 questions, 24%) have been asked the most. Over the last five years the most frequent topics have been Errors of Measurement (3), Addition and Subtraction of Vectors (2), and Fundamentals of Vectors (2). Errors of Measurement has produced the most tough questions (1).
