Q. 15

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

B. I1 = I2

C. I1 > I2

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

Answer :

Density of iron is 7.874 g/cm3 and aluminum is 2.74 g/cm3.



Hence I1 <I2
