What is moment of inertia of a sphere?
Correct answer: C. 2/5 MR2
- A. MR2
- B. 1/2 MR2
- C. 2/5 MR2
- D. 1/2 M2R
Explanation
Please note that the correct option for the moment of inertia of a sphere is c) (2/5)MR2. The moment of inertia of a solid sphere rotating about its center is (2/5)MR2. This is a key result in rotational dynamics for a uniform solid sphere.

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.
