Question

when we move from the poles to the equator .hence , the value of 'g' decreases .why ?

Answer 1

The poles are closer to the centre as the earth is in an elliptical shape. Thus 'g' is high there. But at the equator, it is wider and thus farther from the centre. So the value of 'g' is lower

Answer 2

Answer:

As the radius of the Earth increases from the poles to the equator, the value of g becomes greater at the poles than the equator.

Explanation:

As, we go at large heights, value of g decreases.
