As shown in figure a particle of mass m moves in the x - y plane with a velocity v along the direction AB. L_{A} is the angular momentum of a particle at A with respect to origin and L_{B} when it is at B then

 

Option: 1

L_{A}>L_{B}

 

 

 


Option: 2

L_{A}<L_{B}


Option: 3

L_{A}=L_{B}


Option: 4

this relation depends upon inclination of line AB

Angular momentum due to translation and rotation both -

\vec{L}= \vec{L_{cm}}+m\left ( \vec{r_{0}} \times \vec{v_{0}}\right )

- wherein

\vec{L_{cm}} represent the angular momentum of the body about center of mass.

 

 

\vec{L}=m(\vec{r}\times \vec{v})

or L=mv\times d

so L_{A}=L_{B}
