Practise 42 VITEEE previous year questions on Nuclear Physics, compiled from papers spanning 2006 to 2023. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.
Nuclear Physics has been asked in 16 of the 18 years of VITEEE papers analysed (2006–2024), with 42 questions in all. 33% of them were easy, 45% moderate and 21% tough. Most of its questions came from 2006, with 6 questions that year. In the last three years (2022–2024) it had 5 questions across 2 papers, about 2.5 per paper.
The chapter's 4 topics are not weighted equally: Radioactivity (18 questions, 43%), Nuclear reactions (10 questions, 24%), and Nuclear energy (7 questions, 17%) have been asked the most. Over the last five years the most frequent topics have been Nuclear energy (2), Radioactivity (2), and Nuclear reactions (1). Radioactivity has produced the most tough questions (7).
