i thnk that a sphere filled with non viscous fluid can be treated as a solid sphere....am i rite....????
anyone???
Suppose a hollow sphere is taken. The Sphere is now filled with a non-viscous fluid. What is the change in the Rotational Kinetic Energy ??

I don't know about my reasoning but the answer will be : no change in Rotational K.E .

yeah as there is no external force there must be no change in k.e bt rotational k.e spcifically???????
