How does value of acceleration due to gravity vary with shape of earth

Explanation

We know that the value of acceleration due to gravity on the.s urface of earth is given by
`g= (GM)/(R^(2))`
The earth is not spherical `R_(("equator")) gt R_(("pole"))`. So, `g_("pole") gt g_("equator")`
Thus, the value of acceleration due to gravity is more at poles than at the equator.
