⏱️ Timestamps - Jump to Your Topic:
00:00:00 - Introduction
00:07:12 - Faraday's visualization: "invisible warriors" & field lines
00:10:17 - E = F/q ; why test charge → 0
00:15:10 - Field lines: source (outward), sink (inward), never cross
00:19:02 - Density ↔ strength; line count matters only for comparison
00:22:21 - Dipole vs. like charges; null point shifts
00:29:38 - Conductors: inside E=0, surface field perpendicular
00:34:12 - Electrostatic shielding: Faraday cage, car, elevator
00:36:48 - Problem 1: 6 charges on circle → net force = 2KQq₀/R²
00:43:08 - Problem 2: Charged rod → integration (2 cm to 12 cm)
00:53:07 - Problem 3: Arc ABC → net field = √2 E
00:55:43 - Problem 4: Ring (radius 2a) → max E at z = ±a
01:12:13 - Problem 5: Charged pendulum → T = √[(mg)² + (qE)²]

📚 Lecture Summary:
In this session, you’ll move step-by-step through the core ideas of Electrostatics, starting from the roadmap of Coulomb’s Law to Electric Field and Gauss’s Law. The lecture beautifully explains Faraday’s field visualization, why test charge must approach zero, and the physical meaning of electric field lines.

You’ll explore important properties of field lines, charge interactions, dipole patterns, and conductor behavior — including electrostatic shielding and real-life applications like Faraday cages.

The second half focuses on high-level numerical problems:
• Force at the center of symmetric charge systems
• Electric field due to rods, arcs, and rings
• Maximum field location using calculus
• Charged pendulum in uniform electric field

The lecture ends with key takeaways and a preview of Gauss’s Law, making it perfect for concept clarity and exam-oriented preparation.

⚡ Ideal for CSIR NET Physics June 2026 aspirants who want both theory + problem mastery in one powerful class!
