Amit buys a few grams of gold at the poles as per the instruction of one of his friends. He hands over the same when he meets him at the equator. Will the friend agree with the weight of gold bought? If not,why? [Hint: The value of $g$ is greater at the poles than at the equator.]

(B) The weight of a body on the Earth is given by the formula $W = mg$.
Where:
$m$ = Mass of the body.
$g$ = Acceleration due to gravity.
The value of $g$ is greater at the poles than at the equator because the Earth is flattened at the poles and bulges at the equator.
Since $W = mg$,the weight of the same mass of gold will be greater at the poles and less at the equator.
Therefore,Amit's friend will not agree with the weight of the gold bought because the weight of the gold decreases when moved from the poles to the equator.
