Can You Solve This JEE Main 2026 Physics Question? | Rotational Dynamics

Описание: In this video, Manish Sir (NIT Patna) explains one of the most important Rotational Motion questions for JEE Main 2026 with an easy trick and clear concept.

📌 Question Discussed (JEE Main 2026 – 24 January Morning Shift):

Two masses 400 g and 350 g are suspended from the ends of a light string passing over a heavy pulley of radius 2 cm. When released from rest the heavier mass is observed to fall 81 cm in 9 s. The rotational inertia of the pulley is ____ kg·m². (g = 9.8 m/s²)

This is a very important Rotational Dynamics + Pulley + Moment of Inertia based question frequently asked in JEE.

This question is very useful for:
✔ JEE 2025 / 2026 / 2027 Aspirants
✔ Class 11 & 12 Students
✔ Physics Lovers
✔ Students preparing for competitive exams

If you understand this video properly, you can solve similar pulley + rotational motion questions in seconds ⏱️
