Two solid cylinders P and Q of same mass and same radius start rolling down a fixed inclined plane from the same height at the same time. Cylinder P has most of its mass concentrated near its surface, while Q has most of its mass concentrated near the axis. Which statement (s) is (are) correct

View answer and explanation

Correct option: D

Cylinder Q reaches the ground with larger angular speed

Option D (Cylinder Q reaches the ground with larger angular speed) is correct because cylinder Q has a smaller moment of inertia, leading to a larger angular speed at the bottom of the incline.
