The acceleration of a free fall due to gravity is not a constant everywhere on the Earth’s surface because
- mass of the earth
-
elliptical shape of the earth
- variation in the density of the earth
- rotation of the earth about its axis
The correct answer is: B
Explanation
The elliptical shape of the Earth: The Earth is not a perfect sphere; it is slightly flattened at the poles and bulging at the equator. This shape causes variations in gravitational acceleration.
