The moment of inertia of a rod about an axis through its centre and perpendicular to it is 1/12 ML² (where M is the mass and L, the length of the rod). The rod is bent in the middle so that the two halves make an angle of 60°. The moment of inertia of the bent rod about the same axis would be
Options
(a) (1/48) ML²
(b) (1/12) ML²
(c) (1/24) ML²
