Three thin rods each of length Land mass M are placed along x, y and z

1.	Three thin rods each of length Land mass M are placed along x, y and z-axes such that one of each rod is at origin. The moment of inertia of this system about z-axis isA. `2.3ML^(2)`B. `(4ML^(2))/3C. `(5ML^(2))/3D. `(ML^(2))/3
Answer» a) Moment of inertia of the rod lying along z-axis will be zero. MI of the rods along x and y-axes will be `(ML^(2))/3` each. Hence, total moment of inertia is `2/3` M`L^(2)`.
