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
