QAIPMT-2008-Ph-2272: NEET 2008 Physics - Class 11 AIPMT-2008-Ph-2272 Solution: A thin rod of length L and mass M is bent at its midpoint into…

A thin rod of length L and mass M is bent at its midpoint into two halves so that the angle between them is

90^\circ

. The moment of inertia of the bent rod about an axis passing through the bending point and perpendicular to the plane defined by the two halves of the rod is

Multiple Choice Options

A $\frac{ML^2}{6}$
B $\frac{\sqrt{2}ML^2}{24}$
C $\frac{ML^2}{24}$
D $\frac{ML^2}{12}$

Step-by-Step Verified Solution

Total mass = M, total length = L Moment of inertia of OA about O = Moment of inertia of OB about O. _ M.I total = 2 _ ( M 2 ) ( L 2 ) 2 . 1 3 = M L 2 12
