Introduction & Scope

Topic 68 is the single highest-scoring topic in the entire Paper II Science & Technology unit with 66 marks over 6 years and an average of 13.2 marks per exam. It appeared in all five exam years.

Physics underpins the entire science curriculum, and the RPSC examiner draws heavily from applied physics — medical diagnostics, nuclear energy, and everyday electrical phenomena.

2026 High-Priority Sub-domains:

• Medical diagnostics (MRI, CT, PET, Ultrasound) — appeared in 2021, heavily expected again
• Nuclear fission/fusion — with India's expanding nuclear programme and ITER membership
• EM waves and their applications — consistently tested
• Semiconductor/band theory — tested 2016; likely revisited in 2026

Strategy for 50-word answers: Use the formulaic approach — state the law/principle → key equation or number → one practical application. Physics questions reward specific numbers (velocities, frequencies, energies).
