Gravity Problem: Equator vs Poles - What Happens?

[anigeo]

if the Earth stops rotating , the value of 'g' will increase by Rω² at the equator but will remain same at the poles.how does it happen?could you please explain me this?

Imagine something was resting on a scale (such as a bathroom scale). What determines the reading of the scale? (Apply Newton's 2nd law.)

Can u be a little more precise.i could not get what u said.

What didn't you understand?

Imagine you are at the equator standing on a scale. The scale reads your apparent weight. If the Earth stopped rotating, how would the reading change?

then doc, what about the poles?

When you figure out the answer at the equator, the answer at the poles will be clear.

i got the point clearly`.
thanx.
