Question

The value of gravitational acceleration (g) is _ _ _ _.


1) highest at the poles
2) highest at the equator
3) same everywhere on the surface of the earth
4) lowest at the poles​

Answer 1

Answer:

1) highest at the poles

Explanation:

Expression for acceleration due to gravity is given by -

g = GM/R^2

as we know radius of earth at poles is minimum, so acceleration due to gravity will be maximum at poles because g is inversely proportional to R^2

Also net acceleration due to gravity is affected by centrifugal force due to rotation of earth
