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 `vec L` about the origin ?

A

`barL= (mv)/(sqrt(2))R hatk` when the particle is moving from D to A

B

`barL= -(mv)/(sqrt(2))R hatk` when the particle is moving from A

C

`barL= mv[(R )/(sqrt(2))-a] hatk` when the particle is moving from C to D

D

`barL= mv[(R )/(sqrt(2))+a] hatk` when the particle is moving from B to C.
