Please copy your link directly from the browser to your message, rather than using a displayed version of the URL: the ellipsis ( the ... ) is currently part of your link, so it will not take the reader to the page you are referring to. (Protip: always test your embedded links when posting a message.)

Thread 'Magnitude of buoyant force in fluids of different densities'

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
