A thin rod of length L and mass M is bent at itsmidpoint into two halves so that the angle betweenthem is 90°. The moment of inertia of the bent rodabout an axis passing through the bending point andperpendicular to the plane defined by the two halvesof the rod is[AIPMT (Prelims)-2008]ML2242(1) 2M24MLML2(3) 12 |

Answer» by bending the rods two rods pf mass m/2 and length l/2 are formed so moment of inertia about an axis at the point of bending and perpendicular to the plane is= ML2/24+ML2/24=ML2/12 |
