A rod of mass 2 kg ad length 2 m is rotating about its one end `O` with an angular velocity `omega=4rad//s`. Find angular momentum of the rod about the axis rotation.
Text Solution
Verified by Experts
In pure rotational motion of a rigid body, component of total angualr momentum about axis of rotation is given by `L=Iomega=((ml^(2))/(3))omega` `(I_(0)=(ml^(3))/(3))` Substituting the value we have, `L=((2)(2)^(2))/(3)(4)` `=(32)/(3)kg-m^(2)//s` direction of this component is perperdicular to paper inwards (from right hand rule), as the rotation clockwise.
