Two spheres $A$ and $B$,each of mass $5 \ kg$,are attached to the ends of a light rod of length $1 \ m$. Treating the spheres as point masses,find the ratio of the moment of inertia of the system about an axis passing through $A$ to that about an axis passing through the center of the rod,both axes being perpendicular to the rod.

  • A
    $1 : 1$
  • B
    $1 : 4$
  • C
    $1 : 2$
  • D
    $2 : 1$
