KINDLY EXPLAIN THIS Q,IT'S VERY IMPORTANT.

  A small mass m is attached to a mass less 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 centre at O and constant angular speed. If the angular momentum of the system, calculated about O and P are denoted by and respectively, then
