1- The density of fresh water is 1000 kg/m². The pressure gauge on the submarine in
a river was reading 100 kPa when it was at the surface. A sailor notices that the
gauge is now reading 250 kPa. How deep is he? How would this answer change if
the sailor were diving in sea water is slightly denser than fresh water? [3]​

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
