The Attempt at a Solution



I am not quite sure whether my choice for R and the boundaries of the integral are correct.
The solution seems to be legit at first sight, but as I'm just getting started with integrals, I would very thankful for any feedback or advice.

Well, no one? Do I need to type out my solution? Thought it was okay to scan it.
 

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?
