A small mass m is attached to a massless string whose other end is fixed at P as shown in the figure. The mass is undergoing circular motion in the x-y plane with center at O and constant angular speed $ω$ . If the angular momentum of the system calculated about O and P are denoted by ${\to L}_{0} a n d {\to L}_{r}$ respectively, then
