# Gravitation on three uniform spheres

Lets say we have three spheres all of uniform density and equal mass, However, sphere A has a rotational period of 16h, B has period of 24h and C has period of 48h.
So which one has the greatest acceleration (g value) at the poles and at the equator.

I am sorely tempted to say that, since they all have the same size and density, they all have the same GRAVITATIONAL acceleration.
