The discussion focuses on demonstrating that the tangential components of electric fields at the interface of two dielectric media are equal. Participants suggest using Maxwell's equations as a key tool for solving the problem. The question is derived from a past exam and is considered straightforward, worth only one mark. A hint is provided, emphasizing the importance of Maxwell's equations in the solution process. Overall, the conversation centers on finding a method to prove this principle in electromagnetism.

The Attempt at a Solution



hi this is a part of a question from a past exam which i am trying to do. it is only worth one mark so i am assuming its not hard. any ideas to get me started because I am stumped. thanks

HINT: You need to use one of Maxwell's equations.
 
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?
