A block of mass 8 kg is placed on a wedge of mass 16 kg as shown in the figure. The wedge is free to move on a smooth horizontal surface. All surfaces are frictionless. The acceleration of the block with respect to the wedge is: In this video, we solve one of the most conceptual questions from JEE Main 2021 (September Shift 2) involving a block on a movable wedge. Most students directly apply and end up with the wrong answer. In this lecture, you'll learn: ✅ Why the wedge moves backward ✅ Difference between actual and relative acceleration ✅ Center of Mass concept in wedge problems ✅ Movable wedge formula derivation ✅ Fast JEE exam approach ✅ Common mistakes to avoid Question Details Block mass = 8 kg Wedge mass = 16 kg Inclination = 30° Frictionless surfaces Final Answer: 📚 Topics Covered #JEEPhysics #JEEMain2021 #WedgeProblem #RelativeAcceleration #BlockOnWedge #PhysicsWallah #JEEPreparation #IITJEE #Mechanics #CenterOfMass #PYQ #JEE2026 #JEE2027
