You are presented with the quiz "if an object in a fluid is more dense then it will sink due to whose law?" 

But you don't know the answer, so you turn to your teacher to ask for hints. He says that "if an object in a fluid is more dense than that fluid then that object will sink in that fluid because of gravity" and "for most purposes, Newton's law of gravity is extremely accurate". 

So, what's the best answer to the question?


 

 Newton
