Question

During motion of a man from equator to pole of earth its weight will be

Answer 1

Hello mate.

Thanks for asking such a nice question.

Your answer is =>

As you know that the acceleration gravity is the main cause of changes in weight [= $mg$ ] of body on earth.

We have the relation :-

$\boxed{g\:=\:\frac{GM}{r^{2}}}$

so ,

$=> \boxed{g \:\alpha\:\frac{1}{r^{2}}}$

so , as the radius of earth increases , the value of acceleration due to gravity decreases.

our earth is not absolutely sphere but it is wider on Equator and flattened on Poles.

that means , radius of earth is greater at Equator and Lesser at Poles.

so, according to the relation between acceleration due to gravity and radius of earth ,

acceleration due to gravity is greater on Poles and smaller on Equator.

similarly we say that ,

Our weight is greater at Poles and Smaller at Equator.

so ,

$\underline{when\:a \:Man \:moves \:from\: Equator}$
$\underline{to\: poles\:his \:weight \: increases}$.
