⚡Electrostatics JEE Advanced PYQs with a Fun Twist! 🎮🔋

Charge up your brain cells—let’s crack electrostatics with past JEE Advanced questions turned into mini-games! 🚀

Level 1: Charge Champions (Easy-Moderate)

⚡ Q1. The "Coulomb Chaos" Conundrum (JEE Adv 2020)
Two identical charges q are placed at (0, 0) and (4a, 0). A third charge Q is moved from ∞ to (3a, 0). Calculate the work done.

💡 Fun Angle: Imagine Q is a lazy TikToker—how much "energy drink" (work) does it need to reach the party?
🎯 Answer: >! $\frac{k q Q}{3 a}$ !<
🤯 Pro Tip: Use potential difference, not force. ∞ is free!

Level 2: Gauss’s Galaxy (Moderate)

⚡ Q2. The Sneaky Spherical Shell (JEE Adv 2019)
A conducting shell with charge Q has a charge q placed inside its cavity. What’s the charge on the inner and outer surfaces?

💡 Fun Angle: Think of the shell as a drama queen—inner surface cries -q, outer surface flexes Q + q.
🎯 Answer: >!Inner: $- q$ , Outer: $Q + q$ !<
🤯 Pro Tip: Induction is the key! Charges on conductors always chill on surfaces.

Level 3: Capacitor Crushers (Moderate-Hard)

⚡ Q3. The "Dielectric Drama" (JEE Adv 2017)
A parallel-plate capacitor with dielectric K is half-filled. Calculate the new capacitance.

💡 Fun Angle: It’s like a sandwich—half mayo (dielectric), half bread (air). Mix recipes!
🎯 Answer: >! $\frac{C_{0}}{2} (1 + K)$ !<
🤯 Pro Tip: Treat each half as separate capacitors in parallel!

Level 4: Brain Melt (Hard)

⚡ Q4. The Electric Field Escape Room (JEE Adv 2022)
A non-conducting ring of radius R has charge Q. Find the electric field at a point x on its axis.

💡 Fun Angle: Imagine the ring is a Netflix buffering circle—integrate tiny charges to unlock the answer!
🎯 Answer: >! $\frac{k Q x}{(R^{2} + x^{2})^{3 / 2}}$ !<
🤯 Pro Tip: Symmetry cancels y-components—only x survives!

Level 5: Assertion-Reason Riddles

⚡ Q5.
Assertion (A): Electric field inside a conductor is zero.
Reason (R): Charges repel to the surface.

💡 Fun Angle: If A is Instagram fame and R is filter skills, are they BFFs?
🎯 Answer: >!Both true, and R explains A.!<

🔥 Quick Revision Cheat Sheet

Coulomb’s Law: $F = \frac{k q_{1} q_{2}}{r^{2}}$ (It’s Tinder for charges!)
Gauss’s Law: $ϕ = \frac{Q_{enc}}{ϵ_{0}}$ (Flux = VIP charges only!)
Capacitance: $C = \frac{Q}{V}$ (How much charge can you store per volt?)

🎯 Final Boss Level: The "JEE Finale"
⚡ Q6. (JEE Adv 2021)
Three charges form an equilateral triangle. Find the dipole moment if one charge is removed.

💡 Fun Angle: It’s like Squid Game—remove one player, chaos ensues!
🎯 Answer: >! $q d$ (Dipole moment = charge × distance)!<
