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
