Electric Dipole in 20 Min – Axial & Equatorial Field FULLY Derived | Lec 18 | Class 12 Physics

⚡ Lecture 18 — Electric Dipole | Class 12 Physics | Chapter 1: Electrostatics Dr Kedar Pathak | CBSE & JEE Main In this lecture, we build a complete understanding of the electric dipole — from definition to full derivations — with step-by-step concept reveals and solved problems. ━━━━━━━━━━━━━━━━━━━━━━━━ 📌 WHAT'S COVERED ━━━━━━━━━━━━━━━━━━━━━━━━ ✅ What is an electric dipole? Definition & real-world examples (HCl, H₂O) ✅ Electric dipole moment p = q × 2l — magnitude, direction, SI unit ✅ Problem 1: Finding dipole moment from coordinates (NCERT Example) ✅ Problem 2: Net dipole moment for charges at vertices of an equilateral triangle ✅ Electric field on the AXIAL line — full derivation → E = 2p/r³ ✅ Electric field on the EQUATORIAL line — full derivation → E = p/r³ ✅ The Golden Rule: E_axial : E_equatorial = 2 : 1 (and why!) ✅ Direction of E relative to p⃗ on both lines ✅ Comparison table: axial vs equatorial — everything in one place ✅ 3 Practice problems including the general-angle formula √(1 + 3cos²θ) ━━━━━━━━━━━━━━━━━━━━━━━━ 📚 USEFUL FOR ━━━━━━━━━━━━━━━━━━━━━━━━ • CBSE Class 12 Board Exam (Chapter 1 — Electrostatics) • JEE Main — Electrostatics is ~10–12% of Physics paper • NCERT Exercise + Exemplar problems on dipoles ━━━━━━━━━━━━━━━━━━━━━━━━ 🔔 SUBSCRIBE for the full Class 12 Physics playlist 👍 LIKE if this helped you — it really helps the channel grow! 💬 Drop your doubts in the comments #ElectricDipole #Class12Physics #JEEMain #CBSE #Electrostatics #DrKedarPathak
