Practise 70 JEE Main previous year questions on Experimental Physics, compiled from papers spanning 2008 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 JEE Main tests.

Experimental Physics has been asked in 17 of the 25 years of JEE Main papers analysed (2002–2026), with 70 questions in all. 43% of them were easy, 47% moderate and 10% tough. Most of its questions came from 2024, with 12 questions that year. In the last three years (2024–2026) it had 20 questions across 49 papers, about 0.4 per paper.

The chapter's 2 topics are not weighted equally: Experimental Physics (69 questions, 99%) and Vernier Callipers (1 question, 1%) have been asked the most. Experimental Physics has also led over the last five years, with 35 questions. Experimental Physics has produced the most tough questions (7).
