Question

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 center at O and constant angular speed omega. If the angular momentum of the system, calculated about O blankand 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

  1. stack L with rightwards arrow on top subscript O end subscript and stack L with rightwards arrow on top subscript P end subscript do not vary with time    
  2. stack L with rightwards arrow on top subscript O end subscript varies with time while stack L with rightwards arrow on top subscript P end subscript remains constant    
  3. stack L with rightwards arrow on top subscript O end subscript remains constant while stack L with rightwards arrow on top subscript P end subscript varies with time    
  4. stack L with rightwards arrow on top subscript O end subscript and stack L with rightwards arrow on top subscript P end subscript both vary with time    

The correct answer is: stack L with rightwards arrow on top subscript O end subscript remains constant while stack L with rightwards arrow on top subscript P end subscript varies with time
