MCQEasyJEE Main 2026 · 23 January, Shift 1Moment of Inertia & Radius of Gyration

Two small balls with masses $m$ and $2m$ are attached to both ends of a rigid rod of length $d$ and negligible mass. If angular momentum of this system is $L$ about an axis ( $A$ ) passing through its centre of mass and perpendicular to the rod then angular velocity of the system about $A$ is:

A
$\frac{2L}{5md^2}$
B
$\frac{4}{3} \frac{L}{md^2}$
C
$\frac{3}{2} \frac{L}{md^2}$
D
$\frac{2L}{md^2}$
