A solid sphere and solid cylinder of same mass and density, rotate about their own axis. The moment of inertia will be greater for:
Correct answer: A. Solid sphere
- A. Solid sphere
- B. Solid cylinder
- C. The one that has the largest mass arrives first
- D. The one that has the largest radius arrives first
Explanation
Please note that the correct option for the object with the greater moment of inertia is a) Solid sphere. The moment of inertia of the solid sphere is greater than that of the solid cylinder when both have the same mass and density.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
