Question
A uniform rod of mass 'm' and Length 'L' is rotated about its perpendicular bisector at an angular speed ω. Calculate its angular momentum about its Axis of rotation?
Options:
A .  ML212ω
B .  2ML212ω
C .  32ML23ω
D .  ML224ω
Answer: Option A
:
A
The situation is depicted in the figure shown,
As we know, for this rigid body,
|L| = Iω
= ML212ω {where I = moment of Inertia of rod about its axis of rotation}
