Charged Particle in Magnetic Field: r vs E Graph in 59 Sec 🔥
❓ Concept 🎬 Charged Particle in Magnetic Field — r vs E Graph in 59 Sec Charged particle magnetic field mein gaya… energy badhi … par sawal yeh hai 👇 👉 radius linearly badhega ya curve banayega? ⚡🤔 Is concept ko pakad liya, toh graph-based magnetism questions JEE mein free ho jaate hain 🔥 🖼️ Concept Image ✍️ Short Explanation Yeh question calculation ka nahi , relation samajhne ka test hai. Bas teen steps yaad rakho — force → speed → energy . 🔹 Step 1 — Magnetic Force Causes Circular Motion (FOUNDATION 💯)** Jab charged particle ki velocity magnetic field ke perpendicular hoti hai: q v B = m v 2 r qvB=\frac{mv^2}{r} 👉 Magnetic force centripetal force ka kaam karta hai aur particle circular path follow karta hai. 🔹 Step 2 — Radius Depends on Speed Upar wale relation se: r = m v q B r=\frac{mv}{qB} So: r ∝ v \boxed{r\propto v} 📌 Intuition: Zyada speed ⇒ magnetic field ke liye bend karna mushkil Result ⇒ larger radius 🔹 Step 3 — ...
