For Geeks & Brainiacs #11- Orbiting Coin -
You have two identical coins. If you place one above the other, as in the image below, how many times
will the top coin rotate completely (360°) as it orbits around the coin below it before returning to
its original position?
: The answer is NOT once.
: At first glance the answer seems to be once, but that would be the number of times
the coin would rotate around a point before returning to it's original position. Because the coin is
orbiting around another coin, it's actually two revolutions. Try it if you don't believe it!
Do you have a suggestion
for this puzzle (e.g. something that should
be mentioned/clarified in the question or solution, bug, typo, etc.)?
