1.	Let I1 and l2 be the moments of inertia of two bodies of identical geometrical shape, the first made of aluminium and the second of iron.(a) I1 <l2(b) l1=l2(c) l1> l2(d) relation between I1 and l2 depends on the actual shapes of the bodies.
Answer» (a) I₁ < I₂ . Explanation: Aluminum has a lower density than iron hence the first body has lesser mass than the second. And if the shapes of the bodies are same the M.I. is directly proportional to the mass. So the first body will have lower M.I. than the second body.
