Take the effect of bulging of earth and its rotation in account. Consider the following statement:

(A)There are points outside the earth where the value of g is equal to its value at the equator.


(B)There are points outside the earth where the value of g is equal to its value at the poles.


Due to the rotation, the Earth flattens at the pole and bulges at the equator. Hence, for all points having radius equal to the equator of earth will have the same value of g. And the points at the same radius as the pole would have equal values go g. As the points having radius equal to the equator’s radius lie outside the earth, statement A is correct. But the points having same radius as the pole lie inside the earth. Hence, statement B is wrong.
