Explanation:
The free body diagram of the question is shown on the first uploaded image From the question we are told that
The distance between the two poles is
The mass tied between the two cloth line is
The distance it sags is
The objective of this solution is to obtain the magnitude of the tension on the ends of the clothesline
Now the sum of the forces on the y-axis is zero assuming that the whole system is at equilibrium
And this can be mathematically represented as
To obtain we apply SOHCAHTOH Rule
So
