Question

Amit buys few grams of gold at the poles as per
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.]​

Answer 1

Answer:

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.

Explanation:

Answer 2

Answer:

The weighing machine measures this apparent weight and hence the mass indicated by it is less than the actual mass. Our actual mass will be more than 42 kg.
