Stuck on Tension on a Hanging Massive Rope

[disruptors]

Consider a rope with length l and mass per unit length (lambda), hanging vertically. Let y refer to the height of a point P above the bottom of the rope.

What is the tension at point P in the rope?

Thanks alot ppl...

I know the answer should include y but not sure in what way...
