Part A

A dumbell$-$shaped object is composed by two equal masses, $m,$ connected by a rod of negligible mass and length $r.$ If $I_1$ is the moment of inertia of this object with respect to an axis passing through the center of the rod a moment of inertia with respect to an axis passing through one of the masses, it follows that

$I_2>I_1$

$I_1=I_2$
