The value of g is _:

Explanation

The value of ( g ), the acceleration due to gravity, is least at the equator compared to other latitudes. This is primarily due to two factors: rotation and shape. 1. Centrifugal Force: The Earth is not a perfect sphere; it's slightly flattened at the poles and bulging at the equator due to its rotation. The centrifugal force generated by this rotation is highest at the equator, where the Earth's rotation is fastest. This centrifugal force partially counteracts the gravitational force, resulting in a net decrease in the effective gravity at the equator. 2. Shape of the Earth: The Earth's equatorial diameter is larger than its polar diameter. As you move towards the poles, you get closer to the center of the Earth, where gravity is slightly stronger. At the equator, you are farther from the Earth's center, and gravity is slightly weaker. The combination of these factors leads to a decrease in the effective acceleration due to gravity at the equator compared to other latitudes. The actual value of ( g ) at the equator is approximately 9.78 m/s², while at the poles, it's about 9.83 m/s².
