RAS Mains Physics, written by Biresh Sharma Sir and Vikas Gupta Sir and published by Ceramic Academy, covers physics for the RAS Mains examination. The complete book is written in English (Roman script), with no Hindi content, so it suits candidates who will write the descriptive paper in English. This is the New Edition 2026. The book is prepared according to the latest RAS 2026 syllabus. Physics at the Mains stage is explained rather than calculated — the paper asks for the principle behind a phenomenon or an application in a few marks' worth of writing, not for numerical problem solving of the kind an engineering paper sets. A volume written to the notified syllabus supplies that material at the level and length the answer needs.
