							The figure below shows the pencil falling on the frictionless surface and the path traced by its center of mass:
234-36_1.JPG
It can be seen from above that if enough samples of the falling pencil is taken, and the pencil is assumed to be symmetrical such that the center of mass lie at the center of the pencil, then the path traced by the center of mas of the pencil is a circle.
However, in reality there is friction and the shape is not symmetrical therefore the path traced by the center of mass of the pencil is a curved path.

according to the qustion,
the path would be:
x^2 + y^2 = L^2/4
(the equation of a circle whose radii = L/2)...hope this helps
