Angular momentum is momentum in body when it is in circular motion,but here the particle is in the boundary of a square .Why we are using angular momentum here?

answered-by-expert Expert Answer
It is true that the particle is moving along the surface of the square.
However, the question mentions angular momentum about the origin.
If we consider different positions of the particle along the surface then the angle subtended by the
particle about the origin keeps on changing, and hence, there is angular momentum. Here, it does not matter if it is along the square. Circle is just a standard case.
The angular position is changing so angular momentum is to be considered.

A Uniform Disc of diameter R/2 is put over another uniform disc of radius R of same thickness and Density. The peripheries of the two discs touch each other. The Centre of Mass of the system from centre of the big disc is? (I asked this question before but the answer was wrong. They took the Radius as R/2 while it is the Diameter)
