A solid uniform sphere of radius R and mass M has a rotational inertia about a diameter
that is given by (2/5)MR2. A light string of length 3R is attached to the surface and used to
suspend the sphere from the ceiling. Its rotational inertia about the point of attachment at
the ceiling is:
A. (2/5)MR2
B. 9MR2
C. 16MR2
D. (47/5)MR2
E. (82/5)MR
