To solve this problem it is necessary to apply the concepts related to Newton's second Law and its definition of density.
By Newton's second law we understand that,
F = ma
Where,
m = mass
a = acceleration (at this case the gravity acceleration)
In the case of density, we know that it is described as the proportion of mass versus volume, that is,
Where,
m = mass
V = Volume
The total tension of the AB cable would be given by the tension exerted upwards by the water and the tension exerted by the weight, therefore,
Mass can be expressed as,
Therefore the tension in cable AB is 6103.94N
