    Effect of rotation of earth on acceleration due to gravity,  gλ​=ge​−Re​w2cos2λ    where w  is the angular velocity of the rotation of earth and λ is the lattitude.

    Now at poles,  λ=90o
    ⟹ gpoles​= ge​ = constant

    Thus as the earth stops suddenly then gλ​ increases by an amount of Re​w2cos2λ everywhere except at poles.
