Detailed Solution

Acceleration due to gravity (g) depends on rotation of earth as
$g_{ϕ} = g - {Rω}^{2} \cos^{2} ϕ where ϕ = latitude, ω = anguler speed of rotation of earth$
$At poles ϕ = 90^{\circ} \Rightarrow g_{ϕ} = g At equator ϕ = 0^{\circ} \Rightarrow g_{ϕ} = g - {Rω}^{2}$
$∴$ At poles acceleration due to gravity is independent on rotation of earth.
