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?
