what is the charge density at the other end?
A thin rod with length L carries a non-uniform charge density which varies linearly with distance along the rod. The total charge contained in the rod is Q. If the charge density is zero at one end of the rod, what is the charge density at the other end?

Average charge density = Q/L.
That means the charge density at the other end is 2Q/L (because the average of 0 and 2Q/L is Q/L).
