example 7.4b page 63:
why is the mg 36 N pointing down? shouldn't be pointing up because its says it weights in the air and 9 newtons should be ponting down because it specifically says 9 newtons in water? did they know it was already sunken before doing any calculation because of the specific gravity ratio?
So do we always use the specific gravity ratio pobject/pwater for sunken objects only?
I really don't like Fluids !
