Answer:
Tension of 132N
Explanation:
We need to apply Summatory of Force to find the tension in the hand.
We define te tensión in the hand as
and the Tension in fence post as
, then


We apply summatory of moments then

Where the Force 2 is 1.25m from the center of summatory,
We can note that,

We have two equation and two incognites, then replacing (1) in (2)
