1.	Two uniform solid spheres having unequal rdii are released from rest from the same height on a rough incline. Ilf the spheres roll without slippingA. The heavier sphere reaches the bottom firstB. The bigger sphere reaches the bottom firstC. The two spheres reach the bottom togetherD. The information given is not sufficient to tell which sphere will reach the bottom first
Answer» Correct Answer - C `a=(gsintheta)/(1+(K^(2))/(R^(2))),` For any sphere `(K^(2))/(R^(2))=2/5` So, acceleration is independent of mass of radius.
