Question

The ratio of the accelerations for a solid sphere (mass ‘m’ and radius ‘R’) rolling down an incline of angle ‘q’ without slipping and slipping down the incline without rolling is : (a) 5 : 7 (b) 2 : 3 [2014] (c) 2 : 5 (d) 7 : 5

Answer 1

Answer:

maybe 2:3 is correct answer....

Explanation:

.....

Answer 2

Answer:

Correct option (a) 5:7

Explanation:

Acceleration of the solid sphere slipping down the incline without rolling is

a slipping = g sin Theta.

Acceleration of the solid sphere rolling down the incline without slipping is

a rolling by a slipping = 5/7.
