Given values:

The buoyant force on the diver in seawater is .(Previous part of this question)

The diver's weight, along with the downward-pointing gear, puts a vertical strain on them. It's worth noting that they weigh a total of 72.8 kg.

Formula:

 

 

Step-by-step explanation

Step 1.

It is common knowledge that wood and plastic float in water, whereas an iron ball and a stone sink right away. Iron that has been fashioned into a bowl (like a ship) will also float. As a result, we understand that the density of the object's constituent materials has no bearing on whether or not it sinks. Archimedes' principles can be used to explain this phenomenon: the outthrust on a submerged body is equal to the weight of the fluid displaced.
