Suppose that the angular velocity of rotation of the Earth is increased. Then, as a consequence,

Options:

Answer:

Solution:

Effective acceleration due to gravity, $g^{'} = g - ω^{2} R \cos^{2} ϕ$ , where $ϕ$ is latitude. There will be no change in gravity at poles as $ϕ = 90^{o}$ . At other points as $ω$ increases, $g'$ will decrease.
