A straight rod of length L is released on a friction less horizontal floor in a vertical position .
As it falls( also slips) , the distance of a point on the rod from the lower end, which follows a quarter circular locus.
A) L/2   B) L/4  C) L/8  D) None.

Ans) none as no point on the rod makes circular path. Only the lower piont will shift L/2 distancefrom its initial position.
