NEET 2014 Physics Rolling Motion MCQ Question
Type: MCQ-conceptual-Medium-Class 11
The ratio of the accelerations for a solid sphere (mass m and radius R) rolling down an incline of angle 'θ' without slipping and slipping down the incline without rolling is
A
5 : 7
B
2 : 3
C
2 : 5
D
7 : 5
Correct Answer
Option A
Detailed Explanation
For rolling without slipping, the acceleration is (5/7)g sinθ, and for slipping without rolling, it is g sinθ. The ratio is (5/7) : 1, which simplifies to 5 : 7.
