Physics - Nuclear Physics

Practise 80 AP EAMCET previous year questions on Nuclear Physics, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AP EAMCET tests.

Nuclear Physics has been asked in 21 of the 24 years of AP EAMCET papers analysed (2001–2024), with 80 questions in all. 60% of them were easy, 31% moderate and 9% tough. Most of its questions came from 2022, with 10 questions that year. In the last three years (2022–2024) it had 24 questions across 28 papers, about 0.9 per paper.

The chapter's 4 topics are not weighted equally: Radioactivity (38 questions, 48%), Nuclear structure (17 questions, 21%), and Nuclear reactions (17 questions, 21%) have been asked the most. Radioactivity has also led over the last five years, with 18 questions. Nuclear reactions has produced the most tough questions (3).
