उत्तर
(a) the density continuously increases from left to right
(b) the density continuously decreases from left to right
As the density continuously increases/decreases from left to right, there will be difference in the masses of rod that lie on either sides of the centre of mass. Thus, the centre of mass of a rod in such a case will certainly not be at its centre.
