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.]


Weight of an object is given by,

Weight = m*g.


m= mass of the object

g= acceleration due to gravity at that place.

Since the acceleration due to gravity is less at equator as compared to that at poles, the weight of the gold will be less at the equator than at the poles.

Hence, Amit’s friend won’t agree with the weight of the gold bought since it would be less than what he is expecting.
