The value of acceleration due to gravity is maximum at poles and minimum at equator.why ?

Explanation

This is because earth is flattened at poles and it is bluged out at equator.
`:. R_(p)` is minimum and `R_(e)` is maximum.
As `g_(p)=(GM)/(R_(p)^(2))` and `g_(e)=(GM)/(R_(e)^(2))`
There, `g_(p)` is maximum and `g_(e)` is minimum.
