The moment of inertia of a thin uniform rod of length $L$ and mass $M$ about an axis passing through a point at a distance of $1/3$ from one of its ends and perpendicular to the rod is

Options:

Answer:

Solution:

$I_{CM} = \frac{M L ^{2}}{12}$ (about middle point)
$∴$ $I = I_{CM} + M x^{2}$ $= \frac{M L ^{2}}{12} + M (\frac{L}{6})^{2} I = \frac{M L ^{2}}{9}$
