Re: [Phys-L] field of an ellipsoidal distribution



That's a necessary, but not sufficient condition. There's no "horizontal" component at the poles either, but you can't have "lakes" there.

That's cuz the centrifugal force has no (bothersome) "horizontal" component at the equator.

Now let's consider a different case, namely a rigid, strictly
spherical, spinning earth. You can't ask what happens to a
table floating in a lake, because there can't be any lakes.

Nitpick (without significant consequence, but interesting to consider): Technically, you actually can have a "lake" encircling the globe about the equator.
