Answer 1

Answer:

the tension is the greatest force the system

Explanation:

For this exercise we use Newton's second law, in the equilibrium condition, this means that the acceleration is zero a = 0

             

X-axis (horizontal)

           FE - Tₓ = 0

          Fe = Tₓ

Y axis (vertical)

          $T_{y}$ - W = 0

          T_{y} = W

let's use trigonometry for the stress components

           sin θ = Tₓ / T

           Tₓ = T sin θ

           cos θ = T_{y} / T

           T_{y} = T cos θ

we substitute

           FE = T sin  θ  

           W = T cos  θ  

Since the sine and cosine function have values ​​between 0 and 1, the voltage must be greater than the electrical force and greater than the weight of the body.

Therefore the tension is the greatest force the system
