A particle of mass m is moving along the side of a square of side ‘a’, with a uniform speed v in the x-y plane as shown in the figure :

Which of the following statements is false for the angular momentum $$\overrightarrow L$$ about the origin ?
A
$$\overrightarrow L = mv\left[ {{R \over {\sqrt 2 }} + a} \right]\widehat k$$
when the particle is moving from B to C.
B
$$\overrightarrow L = {{mv} \over {\sqrt 2 }}R\widehat k$$
when the particle is moving from D to A.
C
$$\overrightarrow L = - {{mv} \over {\sqrt 2 }}R\widehat k$$
when the particle is moving from A to B
D
$$\overrightarrow L = mv\left[ {{R \over {\sqrt 2 }} - a} \right]\widehat k$$
when the particle is moving from C to D.
