Provided it's the same thickness and width all the way along, the centre of gravity will be atthe six inch mark and in the centre of the ruler. This is provided that there is no, or even spaces at each end. That is to say that the 0" and 12" marks are right at the end or at least the same distance from the end.
The center of gravity on a plastic ruler would typically be located at the midpoint, which is where the ruler balances evenly when placed on a narrow edge or fulcrum. This point is usually at the 15 cm mark on a 30 cm ruler or at the 6 inch mark on a 12 inch ruler.
It depends on what the ruler's made out of. A plastic ruler would inevitably weigh less than a steel ruler.
