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 $x minus y$ plane with centre at $O$ and constant angular speed $omega$ . If the angular momentum of the system, calculated about $O blank$ and $P$ are denoted by $stack L with rightwards arrow on top subscript O end subscript$ and $stack L with rightwards arrow on top subscript P end subscript$ respectively, then
