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.
