Physics - Nuclear Physics

Practise 18 BITSAT previous year questions on Nuclear Physics, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Nuclear Physics has been asked in 14 of the 16 years of BITSAT papers analysed (2009–2024), with 18 questions in all. 39% of them were easy, 44% moderate and 17% tough. Most of its questions came from 2024, with 2 questions that year. In the last three years (2022–2024) it had 5 questions across 5 papers, about 1 per paper.

The chapter's 3 topics are not weighted equally: Radioactivity (10 questions, 56%), Nuclear energy (6 questions, 33%), and Nuclear reactions (2 questions, 11%) have been asked the most. Radioactivity has also led over the last five years, with 4 questions. Nuclear energy has produced the most tough questions (2).
