Three thin rods each of length Land mass...

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 is

A

`2.3ML^(2)`

B

`(4ML^(2))/3

C

`(5ML^(2))/3

D

`(ML^(2))/3

Text Solution

Verified by Experts

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)`.
