At which location on Earth is the value of $g$ maximum? State the reasons.
(N/A) The value of $g$ is maximum at the poles.
Reasons:
$(i)$ The radius of the Earth is slightly smaller at the poles compared to the equator. Since $g = \frac{GM}{R^2}$,a smaller $R$ leads to a larger $g$.
$(ii)$ At the poles,the centrifugal force due to the Earth's rotation is zero,which means there is no reduction in the effective gravitational acceleration.
