Why the value of 'g' is different in poles?
Asked by | 8th Feb, 2014, 04:44: PM
The value of g depends on the radius of earth.
g = GM/R2
Now, earth is not perfectly spherical. It is slightly inflated at the equator and flatter at the poles.
Thus, R near poles is less than R at the equator.
Hence, due to this difference in radii, the value of g is more at the poles than at the equator.
