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' = g - w^2 R $
And at poles $g'=g$
$\therefore $ The value of acceleration due to gravity is minimum at the equator.
