1.	A solid sphere is in rolling motion. In rolling motion a body prosseses translational kinetic energy `(K_(t))` as well as rotational kinetic energy `(K_(r))` simutaneously. The ratio `K_(t) : (K_(t) + K_(r))` for the sphere isA. `10 : 7`B. `2 : 5`C. `5 : 7`D. `7 : 10`
Answer» Correct Answer - C `(K_(t))/(K_(t) + K_(r)) = (1)/(1 + (k^(2))/(R^(2))) = (1)/(1 + (2)/(5)) = (5)/(7)`
