Rotational MotionHard

Question

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

Options

A.Both cylinders P and Q reach the ground at the same time.
B.Cylinders P has larger linear acceleration than cylinder Q.
C.Both cylinders reach the ground with same translational kinetic energy.
D.Cylinder Q reaches the ground with larger angular speed.

Solution



aQ = g sin θ as IQ ~ 0


∴ ωQ > ωP
