Electric Field Lines – Full Numericals Neutral Point, Capacitor Motion & More | Lecture 17

In this lecture, we solve 6 carefully selected numericals on Electric Field Lines — covering CBSE board as well as JEE-level problems. 📌 Problems Covered: ▶ P1 – Two charges +q and −2q: locate the neutral point and find where to place a third charge for zero net force ▶ P2 – Analysing a field line figure (7-part problem): charge ratios, signs, neutral point, lines to infinity, and circular orbit argument ▶ P3 – Grounded metal plate near a point charge +Q: compare electric field and potential at two points ▶ P4 – Particle of charge q and mass m released from rest between parallel plates: find speed at impact using kinematics and energy method ▶ P5 – Electron vs proton in uniform field: (a) who wins the race? (b) who deviates more — for same velocity, same KE, and same momentum? ▶ P6 – Particle projected at 45° inside a capacitor: find maximum speed so it does not hit the upper plate 🔑 Key Concepts: Field line density, neutral points, induced charges, constant acceleration in uniform E field, analogy with free fall, projectile motion in electric field. 📚 Useful for: Class 12 CBSE, JEE Main, JEE Advanced, NEET (conceptual) 🔔 Subscribe for more CBSE & JEE Physics lectures!
