Which one of the following rolling body has 50% translational K.E and 50% rotational K.E?
Correct answer: B. Ring
- A. Disc
- B. Ring
- C. Rod
- D. Sphere
Explanation
Correct answer is B. This option proposes that a ring rolling body has 50% translational kinetic energy and 50% rotational kinetic energy. This is correct. When a ring is rolling without slipping, its total kinetic energy is distributed equally between translational and rotational kinetic energy.

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.
