Vedclass · Answer

(D) The acceleration due to gravity $g$ is given by the formula $g = \frac{GM}{R^2}$,where $G$ is the gravitational constant,$M$ is the mass of the Earth,and $R$ is the distance from the center of the Earth.Because the Earth is not a perfect sphere but is flattened at the poles and bulges at the equator,the radius $R$ is smallest at the poles and largest at the equator.Since $g$ is inversely proportional to the square of the radius $(g \propto \frac{1}{R^2})$,the value of $g$ is maximum where the radius $R$ is minimum.The radius of the Earth is minimum at the poles (Antarctica is located near the South Pole).Therefore,the value of $g$ is maximum at a camp site in Antarctica.

At which of the following locations is the value of $g$ maximum?
