# Let I1 an I2 Be the Moments of Inertia of Two Bodies of Identical Geometrical Shape, the First Made of Aluminium and the Second of Iron. - Physics

MCQ

Let I1 an I2 be the moments of inertia of two bodies of identical geometrical shape, the first made of aluminium and the second of iron.

#### Options

• I1 < I2

• I1 = I2

• I1 > I2

• relation between I1 and I2 depends on the actual shapes of the bodies

#### Solution

I1 < I2

In the given case, we have

MOI

$\propto$ Density

The density of iron is more; therefore, I2 will be greater.

Is there an error in this question or solution?
