SUMMARY
The discussion centers on the gravitational acceleration experienced at the poles and equator of three uniform spheres with equal mass but different rotational periods: 16 hours for sphere A, 24 hours for sphere B, and 48 hours for sphere C. Despite having the same size and density, the net acceleration is influenced by centripetal acceleration, which is proportional to the radius and angular velocity. Sphere C, with the longest rotational period, exhibits the greatest net acceleration at both the poles and equator due to the lowest centripetal acceleration. Thus, the gravitational acceleration remains constant across all spheres, but the net acceleration varies based on rotational speed.
