Yeh true K^2. So it would have to be non-spinning as well as even density throughout.

But Sophie if the gravitational change through the planet - in the above non-realistic but perfect scenario - is linear as Newton's Shell theorem indicates then the gravitational difference between head and toe of the capsule (or indeed the person) would always be the same - irregardless of if they are a point or not - would it not? In this respect the microgravity would remain consistent throughout the journey would it not also?
