Moment of inertia of a long uniform thin rod about an axis passing through its edge and perpendicular to the rod is (Ml2/3) .

Q. Moment of inertia of a rod of length $l$ about an axis passing through its edge is (mass of the rod $M$ )

$\frac{M l ^{2}}{12}$

$\frac{M l ^{2}}{3}$

$\frac{M l ^{2}}{2}$

$\frac{M l ^{2}}{4}$
