The workdone by the tension is; Positive
<h3>What is Tension force?</h3>
This question is from an elevator that is held by a single cable which is ascending but slowing down.
Now, this elevator is being acted upon by two vertical forces known as Tension which is upwards and the weight of the elevator acting downwards.
However, the direction of motion of the elevator is in the same direction as the tension in the cable. Thus, we can say that the work done by tension is positive.
