Answer 1

Answer:

The centrifugal force for the spinning of earth is maximum at the equator and vanishes at the poles. Thus, the gravitational acceleration (g) is minimum at the equator and it is maximum at the poles.

Answer 2

Answer:

Since W= m×g ,

the value of g is greater in high polar region because the centrifugation force of rotation of earth is greater at equator but not in polar parts ...
