A particle of mass

m

moves in the

X Y

plane with a velocity

v

along the straight line

\mathrm{AB}

. If the angular momentum of the particle with respect to origin

\mathrm{O}

L_A

when it is at A and

L_B

when it is at B, then: A particle of mass m moves in the X Y plane with a velocity v along the straight line AB . If the angular momentum of

A $L_A=L_B$
Bthe relationship between $L_A$ and $L_B$ depends upon the slope of the line $\mathrm{AB}$
C $L_A < L_B$
D $L_A>L_{B^*}$

A. $L_A=L_B$

Moment of Momentum is angular momentum. OP is the same whether the mass is at

\mathrm{A}

\mathrm{B}
