Question: I have been wondering about whether if the forces are equal to each other what will happen to Buoyancy and I have come to a conclusion, probably wrong, that it may hang around in the middle of a tank for example?
If the force acting downwards (the weight of the object) is equal to the buoyancy force acting upwards (weight of displaced water), then the forces exactly balance each other!
Since F=ma…
where:
F=Net Force (i.e. difference between weight and buoyancy force) [N]
m= mass [kg]
a= acceleration [m/s²]
…this means that no net force = no acceleration on the object!
Well done on thinking this problem through. Keep it up! 😀
Hope this helps – and remember to vote tomorrow! 😀

Thank you – my idea did seem absurd at the time but now seems logical!
