A hollow sphere of mass MM and radius RR is in pure rolling on the horizontal rough surface. The ratio of rotational kinetic energy to the total kinetic energy of the hollow sphere will be
View answer and explanation
Correct option: A
25\frac{2}{5}
Option A (2/5) is correct because the ratio of rotational kinetic energy to total kinetic energy for a hollow sphere in pure rolling is 2/5.
