1.	A rod of length L is composed of a uniform length L/2 of wood whose mass is m_(w) and a uniform length L/2 of brass whose mass is M_(b)
Answer» The MOMENT of inertia of rod about an axis passing through the CENTRE and perpendicular ot it is `(1)/(12)M_(w)L^(2)`. The moment of inertia rod about an axis as specified in option (1) is `(1)/(12)(M_(w)+M_(b))L^(2)` The moment of inertia of rod about an passing through the wood end and perpendicular th the rod is `1/3(M_(w)+M_(b))L^(2)`. The moment of inertia of rod about an axis as specified in option (3) `(1)/(12)(M_(w)+7M_(b))L^(2)`. Answer :B::D
