the answer is A
all of the above
besides
option B is supposed to be. II, III and IV only.
There are reasons to which the acceleration due to gravity varies on the earth surface and they are
1) the earth is not a perfect sphere
2) variation in density of the earth
3) centrifugal force
So I don’t see where variation in latitudes and longitude came into place
please do well to rectify this question
three different CBT apps chose three different answers
that too, some of the questions are wrongly marked thereby reducing our scores and confusing us as well. please do well to rectify them
Contributions to the question is not related to the question. I've noticed this in other questions too. Please fix this
