A hollow sphere (`i`) rolls and (`ii`) slides down an inclined plane.

1.	A hollow sphere (`i`) rolls and (`ii`) slides down an inclined plane. The ratio of the accelerations in the two cases isA. `3 : 4`B. `3 : 5`C. `2 : 3`D. `5 : 7`
Answer» `a_(1)=(gsin theta)/(1+k^(2)//R^(2))=(g sin 30^(@))/(1+2//3)=(3 g sin theta)/(5)` `a_(2)= g sin theta` `(a_(1))/(a_(2))=(3)/(5)`
