A bird of mass I kg stands on the midpoint of a telephone wire of length 50 m that suspends between two pillars, so that the midpoint of the wire moved by a vertical distance of 0.2 m. Calculate the magnitude of the tension force (FT) that acts on
the wire because of the bird (neglecting the wire's weight). (g = 9.8 m/s)​
