When a 75 kg diver displaces a volume of 70 L the buoyant force acting on the diver
The total applied force per unit of area is known as the pressure.
The pressure depends both on externally applied force as well the area on which it is applied.
As given A 75 kg diver displaces a volume of 70 L.
1000 L = 1m³
1 L = 1/1000 m³
70 L = 70/1000 m³
=0.07 m³
The buoyant force = the weight of the water displaced
=ρgV
=1000×9.81×0.07
=686.7 N
