A thin metal rod of mass 'M' and length 'L' is cut into four equal parts by cutting it perpendicular to the length. If moment of inertia of the rod about an axis passing through its centre and perpendicular to its axis is 'I', then moment of inertia of each part about the similar axis is

Answer: (A)

Solution

For the original rod, . Each of the four equal parts has mass and length . About a perpendicular axis through its own centre, \dfrac{1}{12}\dfrac{M}{4}\dfrac{L}{4}$ =
