A particle of mass $m$ moves in the XY plane with a velocity v along the straight line $AB$. If the angular momentum of the particle with respect to origin $O$ is $L_A$ when it is at $A$ and $L_B$ when it is at $B$, then : <img src =""/>

Question

( A ) The relationship between $L_A$ and $L_B$ depends upon the slope of the line AB
( B ) $L_A ( C )$L_A = L_B$( D )$L_A > L_B$
