Question

The value of gravitational acceleration (g) is ______ at the equator.

Options

• 9.78 m/s²

• 9.832 m/s²

• 9.8 m/s²

• 6.67 m/s²

Answer 1

The value of gravitational acceleration (g) is 9.78 m/s² at the equator.

Explanation:

g varies slightly with latitude because the Earth bulges at the equator and its rotation produces a centrifugal effect that reduces effective gravity there. As a result, g is highest `(~9.832 m/s^2)` at the poles and lowest `(~9.78 m/s^2)` at the equator.
