What is neutral buoyancy
What do you mean by the term neutral buoyancy? Briefly illustrate it.
Expert
Buoyancy is the total upward force experienced by the object submersed in the fluid. Pascal's principle states that fluid pressure on an object rises with depth, thus there is a greater pressure on the bottom of object than the top, resultant in a total upward force. Whenever an object's buoyancy is bigger than its weight, then the object will float.
