# Which will win the race?

As the image shows, $$O$$ is the center of a circle, $$E$$ is at the bottom of the circle, and $$AE,BE,CE,DE$$ are all smooth inclines along the circle.

Now, let's put four balls at rest at points $$A,B,C,D.$$

If whichever gets to point $$E$$ first wins the race, ignoring all the frictions, which ball will win the race?
