Question

The acceleration due to gravity on the surface of earth varies :

• A. directly with longitude
• B. directly with latitude
• C. inversely with longitude
• D. inversely with altitude

Answer 1

The correct option is B directly with latitude

The acceleration due to gravity is maximum at poles and minimum at the equator because the centrifugal force for the spinning of earth is vanishes at poles and maximum at the equator. The latitude at the equator is $0^o$ and at the poles is ${90}^o$.
