NEET2014PhysicsRotational MotionActual
The ratio of the acceleration 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:
Options
- A5 : 7
- B2 : 3
- C2 : 5
- D7 : 5
Correct answer
A. 5 : 7
Step-by-step solution
a 1 = g sin ⁡ θ 1 + I M R 2 a 2 = g sin ⁡ θ 1 + 2 5 M R 2 M R 2 = 5 7 g sin ⁡ θ a 1 a 2 = 5 7
