Vedclass · Answer

(B) The Earth is not a perfect sphere; it is flattened at the poles and bulges at the equator. As a result,the radius of the Earth at the equator $(R_e)$ is greater than the radius at the poles $(R_p)$. The formula for acceleration due to gravity is $g = \frac{GM}{R^2}$. Since $g$ is inversely proportional to the square of the radius $(g \propto \frac{1}{R^2})$,a larger radius at the equator results in a smaller value of $g$. Therefore,as we move from the poles towards the equator,the value of $g$ decreases.

As we move from the poles of the Earth towards the equator,what happens to the value of the acceleration due to gravity $(g)$?
