Each chapter includes a dedicated section for ISC Previous Years’ Questions. This helps students understand the exam pattern, marking scheme, and frequently asked topics. There’s no separate need for a past-paper bank.
The book is structured specifically to cater to the ISC syllabus, which differs slightly from CBSE/NCERT in terms of depth and specific topics. isc nootan physics class 12
Unlike purely theoretical books, Nootan Physics includes problems that connect physics to real devices: Each chapter includes a dedicated section for ISC

Chapter 2: Electric Field & Potential
Level 1: Two point charges ( +4\mu C ) and ( -2\mu C ) are placed 10 cm apart. Find the force between them.
Level 2: Three charges ( q, 2q, -q ) are placed at vertices of an equilateral triangle of side ( a ). Find net force on ( q ).
Level 3: A charged ring of radius ( R ) has total charge ( Q ). Find electric field at a point on its axis at distance ( x ) from center. If ( x \gg R ), show that field behaves like a point charge. (ISC 2018 modified)
