A uniform cable of weight w hangs vertically downward,supported by an upward force of magnitude w at its top end. What is the tension in the cable (a) at its top end; (b) at its bottom end; (c) at its middle? Your answer to each part must include a free-
body diagram. (Hint: For each question choose the body to analyze
to be a section of the cable or a point along the cable.) (d) Graph
the tension in the rope versus the distance from its top end.
Newtons first law since the body is not accelerating.

Actually i am not able to understand the problem itself. Particularly i am not able to understand the sentence "supported by an upward force of magnitude w at its top end" in the above problem statement. Kindly explain me??
