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 centre at O and constant angular speed `omega`. If the angular momentum of the system. calculated about O and P are denoted. by `vecL_O and vecL_P` respectively, then.

Options

A. `vec(L)_(0) and vec(L)_(p)` do not vary with time
B. `vec(L)_(0)` veries with time while `vec(L)_(p)` remains constant
C. `vec(L) _(0)` remains constant while `vec(L)_(p)` varies with time
D. `vec(L)_(0)and vec(L)_(p)` both very with time

Answer

C
