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

Expert Answer
Hence, option (C) is the correct answer.
The vector L depends on the radius vector. Hence, for two diferent points on the same line, radius vector is different.
Thus, L is different for two points on the same line vector.
