Q10 of 149 Page 194

A hollow sphere and a solid sphere having same mass and same radii are rolled down a rough inclined plane.


Looking into the fig. –



But




or



But from the parallel axis theorem -




We know that the object with the smallest mass moment of inertia (IC) will have the largest acceleration down the plane.


Solid Sphere:



And for Hollow Sphere:
