Question
A small mass 
is attached to a massless string whose other end is fixed at 
as shown in the figure. The mass is undergoing circular motion in the 
plane with center at 
and constant angular speed 
. If the angular momentum of the system, calculated about 
and are denoted by 
and 
respectively, then
- and do not vary with time
- varies with time while remains constant
- remains constant while varies with time
- and both vary with time
and do not vary with time
varies with time while remains constant
remains constant while varies with time
and both vary with time
The correct answer is: remains constant while varies with time
