Answer the following question in detail.
At which place on the Earth’s surface is the gravitational acceleration maximum? Why?
- Gravitational acceleration on the surface of the Earth depends on the latitude of the place as well as the rotation and shape of the Earth.
- At poles, latitude θ = 90°.
∴ g' = g
i.e., there is no reduction in acceleration due to gravity at poles.
- Also, shape of the Earth is actually an ellipsoid, bulged at equator. The polar radius of the Earth is 6356 km which minimum. As
g ∝ `1/"R"^2`, acceleration due to gravity is maximum at poles i.e., 9.8322 m/s2.
Concept: Variation in the Acceleration Due to Gravity with Altitude, Depth, Latitude and Shape
