A dumbbell-shaped object is composed by two equal masses, m, connected by a rod of negligible mass and length r. If I_1 is the m

Vanyuwa [196]

Answer: $I_2>I_1$

Explanation:

Given

Shape of the object is dumbbell shaped

Moment of Inertia w.r.t an axis passing through center and perpendicular to it

$I_1=m(\frac{r}{2})^2+m(\frac{r}{2})^2$

$I_1=\frac{mr^2}{2}$

For the axis which passes through one of the masses

$I_2=mr^2$

so $I_2>I_1$
