. 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

Answer: The weight of a body on the earth’s surface;

W = mg (where m = mass of the body and g = acceleration due to gravity)

The value of g is larger at poles when compared to the equator. So gold can weigh less at the equator as compared to the poles.

Therefore, Amit’s friend won’t believe the load of the gold bought.
