A thin rod of length L is lying on the X-axis with its end at x = 0 and x = L. Its linear density varies with x as K(x/L)^(n) ,where n can be zero or any positive number. If the position of centre of mass of the rod is plotted against .n. which of the following graph best approximates the dependence of X_("cm") on n ?

1.	A thin rod of length L is lying on the X-axis with its end at x = 0 and x = L. Its linear density varies with x as K(x/L)^(n) ,where n can be zero or any positive number. If the position of centre of mass of the rod is plotted against .n. which of the following graph best approximates the dependence of X_("cm") on n ?
