Today as we were discussing gravitation and space, a student asked the
following:
On Earth a helium filled balloon rises because of bouyancy. How would the
same helium filled ballon move in a spacecraft (eg space shuttle cabin) if
it was
a) in orbit around Earth
b) in "deep" space
I would be interested in how you would answer this question.
