Class 12 Physics 2025-26 | Chapter 1: Electric Charges and Fields | Previous Year Question (PYQ) with detailed explanation. In this video, we solve PYQ Question (AI 2017): "Use Gauss’s theorem to find the electric field due to a uniformly charged infinitely large plane thin sheet with surface charge density σ." We explain step by step using Gauss’s law to derive the expression of the electric field due to an infinite plane sheet of charge. This is an important derivation for CBSE Class 12 Physics Board Exam 2025-26 as well as for competitive exams like JEE, NEET. 🔹 Detailed derivation using Gauss’s theorem 🔹 Important for exams (2/5 marks question) 🔹 Electric field concept explained clearly 🔹 Previous Year Question solved (AI 2017) 👉 Perfect revision for Class 12 Physics students preparing for CBSE Boards, JEE Mains, NEET, and other competitive exams. --- ✅ Playlist: Class 12 Physics 2025-26 | 👉 Ch-1 Electric Charges and Field Class 12th (Single Question in one video): • Ch-1 PYQs Electric Charges and Field Class... 👉 12th Physics PYQs Chapter 1 | Electric Charges and Field: • 12th Physics PYQs Chapter 1 | Electric Cha... 📲 Join My Telegram Channel for asking about Doubts , Notes & Updates: 👉 https://t.me/studywithsaif01 --- #Class12Physics #ElectricChargesAndFields #GaussLaw #InfinitePlaneSheet #BoardExam2025 #JEEPhysics #NEETPhysics #PhysicsDerivation #PYQPhysics
