JEE Main: ΔU Depends Only on Start & End 💡
❓ Concept 🎬 Electrostatics — Potential Energy is Path Independent (59 Sec) Charge circular path pe move kare, curve dikhe, arc dikhe… 👉 Par JEE poochta hai sirf start aur end ka khel! ⚡🧠 Electrostatics ka yeh golden rule pakad liya, toh half chapter khud simplify ho jaata hai 🔥 🖼️ Concept Image ✍️ Short Explanation Electrostatic force conservative hoti hai. Matlab energy change path pe depend nahi karta . Isliye circular path sirf distraction hai 😎 🔹 Step 1 — Key Rule: Electrostatic Force is Conservative (FOUNDATION 💯)** Electrostatic field ka sabse powerful rule: Δ U = U f − U i \Delta U = U_f - U_i 👉 Depends only on: Initial position Final position ❌ Path does NOT matter Circular, zig-zag, straight — sab same. 🔹 Step 2 — Potential Energy Change Formula For a charge q 3 q_3 placed in electric field: Δ U = q 3 ( V f − V i ) \Delta U = q_3 (V_f - V_i) ⚡ Sirf potential difference important hai. Force ka work = potential energy change...
