Question
The value of ‘g’a. Increases as we go above the earth’s surfaceb. Decreases as we go to the centre of the earthc. Remains constantd. Is more at equator and less at poles
Solution 1
The correct answer is b. The value of 'g', or the acceleration due to gravity, decreases as we go to the centre of the Earth. This is because 'g' is proportional to the mass of the Earth and inversely proportional to the square of the distance from the center of the Earth. As we move towards the center, the distance decreases, reducing the gravitational pull.
Also, it's worth noting that 'g' is slightly less at the equator than at the poles due to the Earth's rotation causing a slight flattening at the poles and bulging at the equator. So, the distance from the center of the Earth is slightly more at the equator than at the poles, resulting in a slightly lower value of 'g' at the equator.
