18. Identical packets are dropped from two aeroplanes, one above the equator and the other above the north pole, both at height h. Assuming, all conditions are identical, will those packets take same time to reach the surface of Earth. Justify your answer.

Thus, the value of `g’ is minimum at the equator and maximum at the poles. It means `g’ increases as we go from equator to pole. Therefore, the packet falls slowly at equator compared to the poles. Thus, the packet will remain in air for a longer time, when it is dropped at the equator.
