Question

Spot the wrong statement. The acceleration due to gravity $‘g’$ decreases if

• A. we go down from the surface of the Earth towards its centre.
• B. we go up from the surface of the Earth.
• C. we go from the equator towards the poles on the surface of the Earth.
• D. the rotational velocity of the Earth is increased

Answer 1

Answer: (C)

$g=g_p-{\omega }^{2}R{\cos }^2\lambda$
where $\lambda$ is the latitude. The maximum $g$ we have at
$\lambda =90^{\circ }$ or poles.
