JEE Advanced 2015 Physics PYQ | Rotational Motion | Point Mass on Ring

JEE Advanced 2015 Physics PYQ – Rotational Motion In this video, we solve a JEE Advanced 2015 Rotational Motion problem based on a rotating ring, two point masses, and conservation of angular momentum. A ring of mass M and radius R is rotating about a fixed vertical axis. Two point masses move radially outward along massless rods. At a certain instant, the angular velocity changes, and we need to determine the distance of the second mass from the centre. This is an important JEE Advanced problem for understanding how moment of inertia and conservation of angular momentum are applied when masses move radially. 📚 Concepts Covered Conservation of Angular Momentum Moment of Inertia Rotational Motion Variable Moment of Inertia Point Masses on Rotating Rods JEE Advanced PYQ Approach Rotational Dynamics 🎯 Exam: JEE Advanced 📅 Year: 2015 📖 Chapter: Rotational Motion ⚡ Level: JEE Advanced If you find this solution helpful, Like 👍, Share and Subscribe for more JEE Main & JEE Advanced Physics PYQs and concept-based problems. #JEEAdvanced #JEEPhysics #RotationalMotion #AngularMomentum #PhysicsPYQ #JEEMain #JEEPreparation #JEEAdvancedPhysics #Physics
