A thin uniform rod of mass M and length L is bent at its center so the two segments are perpendicular to each other, as shown in the figure. What is the moment of inertia about an axis perpendicular to its plane and passing through the point where the two segments meet. (The moment of inertia of a rod of mass M and length L rotating about its end is 1/3ML2. The moment of inertia of a rod of mass M and length L about its center is 1/12ML) L/2 L/2 O 1/2ML^2 O 1/12ML^2 O 1/3ML^2 O 1/4ML^2 O 1/6ML^2
