Physics - Gravitation
Practise 38 AIIMS previous year questions on Gravitation, compiled from papers spanning 2001 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AIIMS tests.
Gravitation has been asked in 16 of the 19 years of AIIMS papers analysed (2001–2019), with 38 questions in all. 26% of them were easy, 50% moderate and 24% tough. Most of its questions came from 2003, with 5 questions that year. In the last three years (2017–2019) it had 8 questions across 5 papers, about 1.6 per paper.
The chapter's 5 topics are not weighted equally: Motion of satellite (12 questions, 32%), Acceleration Due to Gravity (9 questions, 24%), and Gravitational potential and Potential Energy (7 questions, 18%) have been asked the most. Gravitational potential and Potential Energy has produced the most tough questions (4).
