The value of gravitational acceleration at poles is ______?
The value of gravitational acceleration at poles is ______?
قطبوں پر کشش ثقل ایکسلریشن کی قدر ______ ہے؟
Explanation
The gravitational acceleration (g) is slightly higher at the poles than at the equator due to two main factors:Earth's Shape: The Earth is an oblate spheroid (flattened at the poles), so the poles are closer to the planet's center of mass, increasing g.
Centrifugal Force: The rotational speed of the Earth is lowest at the poles, reducing the outward centrifugal force that counteracts gravity.
Thus, g is strongest at the poles and weaker at the equator.
