Amit buys 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.]

Option A

Option B

Option C

Option D

Solution

Weight of a body on the Earth is given by $W = mg$

Where,

$m = $ Mass of the body

$g =$ Acceleration due to gravity

The value of $g$ is greater at poles than at the equator. Therefore, gold at the equator weighs less than at the poles. Hence, Amit’s friend will not agree with the weight of the gold bought.
