A horizontal clothesline is tied between 2 poles, 14 meters apart. When a mass of 2 kilograms is tied to the middle of the clothesline, it sags a distance of 3 meters. What is the magnitude of the tension on the ends of the clothesline? Isnt the tension just 2g Newtons? or for just one end of the clothesline g Newtons? The website where i enter these problems is not validating these answers. I dont know why. I also did the x componets, the y componets, and the negative of all of that, the answers are never valid. I have no clue why.
