why The value of small ‘g’ does not remain the same along the surface of the Earth?
Answers
Answer : value of g is not constant on earth because gravitation acts from centre of the earth which is not a sphere therefore as the diametre of earth vary from pole to equator so the acc. due to gravity(g) also vary
Explanation : Factors affecting acceleration due to gravity (g): 1. As the height (altitude) increases acceleration due to gravity (g) decreases
2. As the depth increases acceleration due to gravity (g) decreases
3. Local conditions affect the acceleration due to gravity (g) slightly by the geological deposits, massive concrete buildings and topography
4. At the poles acceleration due to gravity (g) is maximum
5. At the equator acceleration due to gravity (g) is minimum
