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? [2012]
(1) Both cylinders P and Q reach the ground at the same time.
(2) Cylinders P has larger linear acceleration than cylinder Q .
(3) Both cylinders reach the ground with same translational kinetic energy.
(4) Cylinder Q reaches the ground with larger angular speed.
