A particle of mass `m` is moving along the side of a square of side `a`, with a uniform speed v in `XY` plane as shown in Fig. Which of the followig statements is false for the angular momentum `overset rarr(L)` about the origin?
A
`vecL=mv[(R)/(sqrt(2))-a]hatk` when the particle is moving from C to D.
B
`vecL=mv[(R)/(sqrt(2))+a]hatk` when the particle is moving from B to C.
C
`vecL=(mv)/(sqrt(2)) R vec k` when the particle is moving from D to A.
D
`vecL=-(mv)/(sqrt(2)) R vec k` when the particle is moving from A to B.
