A thin uniform rod has mass 'M' and length 'L'. The moment of inertia about an axis perpendicular to it and passing through the point at a distance $\frac{L}{3}$ from one of its ends, will be

Options:

Answer:

Solution:

(B) $I h I = I_{0} + Mh^{2} = \frac{L}{2} - \frac{L}{3} = \frac{L}{6} = \frac{ML ^{2}}{12} + Mh^{2} = \frac{ML ^{2}}{12} + \frac{ML ^{2}}{36} = \frac{4 ML ^{2}}{36} = \frac{ML ^{2}}{9}$
