NEET 2018 Physics Rotational Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
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
A
7:10
B
5:7
C
10:7
D
2:5
Correct Answer
Option B
Detailed Explanation
For a solid sphere, the moment of inertia and the relationship between translational and rotational motion determine the ratio of kinetic energies.
