Question

At sea level, the value of $g$ is minimum at

• A. the poles
• B. the equator
• C. $45^{\circ }$ south latitude
• D. $45^{\circ }$ north longitude

Answer 1

Answer: (B)

Due to the rotation of the earth, the acceleration due to gravity for earth changes and at the equator, its value is given by $g^{\prime }=g-w^{2}R$
And at poles $g^{\prime }=g$
$\therefore$ The value of acceleration due to gravity is minimum at the equator.
