Q. What is a neutral buoyancy?
Answer:-
Buoyancy is the net upward force knowledgeable by an object submersed in a fluid. Pascal's principle utters that fluid pressure on an object increases with depth so there is greater pressure on the bottom of the object than the top resulting in a net upward force. When an object's buoyancy is superior than its weight the object will float.
An object with neutral buoyancy has a density such like that when it is fully submerged the upward force due to buoyancy is exactly equal to the downward force due to the weight of the object. In pure water this is the density of 1000 kg/m3 (1kg/litre)
In seawater this is the density of about 1025 kg/m3 (1.025kg/litre)
