1.	A body is rolling down an inclined plane. If `K.E.` of rotation is `40%` of `K.E.` in translatory state, then the body is aA. ringB. cylinderC. hollow ballD. solid ball
Answer» `(K_(R))/(K_(l))=((1)/(2)mv^(2)(k^(2)//R^(2)))/((1)/(2)mv^(2))=(k^(2))/(R^(2))=(40)/(100)=(2)/(5)`, solid sphere, i.e. solid ball
