NEET 2018 Physics Rotational Motion MCQ Question
A solid sphere is in rolling motion. In rolling motion, a body possesses translational kinetic energy (Kₜ) as well as rotational kinetic energy (Kᵣ) simultaneously. The ratio Kₜ : (Kₜ + Kᵣ) for the sphere is
7:10
5:7
10:7
2:5
Correct Answer
Detailed Explanation
For a solid sphere, the moment of inertia and the relationship between translational and rotational motion determine the ratio of kinetic energies.
