A submarine can either sink or float even though the upthrust acting on it is the same. What is the relationship between the weight of the submarine and the upthrust when the submarine sinks in water?
The figures below show that a submarine can either sink or float even though the upthrust acting on it is the same. What is the relationship between the weight of submarine and the upthrust when the submarine sinks in water?
Upthrust is equal to the weight of the displaced liquid.
