Episode Synopsis

Value of G is constant whereas the value of small g changes from place to place as earth is not a perfect sphere.Its radius at poles is smaller than that at equator,so the value of g is more at poles than that of equator as the g is inversly proportional to the radius.At the centre of earth the value of g becomes zero.
