Question

The maximum reduction in the acceleration due to gravity (g) due to Earth's rotation occurs at which location?

Options

• The Poles (θ = 90°)

• 45° Latitude

• The Equator (θ = 0°)

• The Tropic of Cancer

Answer 1

The Equator (θ = 0°)

Explanation:

At the Equator, cos 0° = 1, making the reduction term Rω² cos² θ a maximum, resulting in minimum g'.
