As we move from the equator towards the poles, the value of g decreases (B). This is due to the centrifugal force caused by Earth’s rotation, which is greatest at the equator and decreases towards the poles. Additionally, the shape of the Earth is not a perfect sphere; it’s slightly flattened at the poles and bulging at the equator. This variation in distance from the Earth’s center also affects the gravitational force. As we move towards the poles, we are closer to the Earth’s center, resulting in a stronger gravitational force. However, this increase is offset by the decrease in centrifugal force, leading to a net decrease in the value of g. This decrease is not constant but varies gradually as we move from the equator towards the poles, reaching its maximum value at the poles. Therefore, the correct option is (B) decreases.
