This is the question I got at my York Uni interview, he drew I diagram for me and so I'll also try drawing and posting one.
here's the question:
and cylindrical glass is partially filled with water. The glass is tipped so that the water is a point at the open end (reaches but does not spil over) of the glass and just crosses the diameter of the bottom of the glass at the bottom.
Does the water in this glass fill 1/4, less than 1/4 or more than 1/4 of the glass and why?
OK, now my attempt at a diagram.
