Moment of inertia of given rod is
Explanation:
As the rod is spinning on its own centre , we are considering the moment of inertia of rod with axis perpendicular to rod at midpoint i.e.,
This can be done by calculating the moment of inertia of a system
Now calculating the moment of inertia of rod with given values we get
