Solution

The weight of a body is given by:
W = mg
where, m = Mass of the body
g = Acceleration due to gravity at that place
The value of g is greater at poles as compared to the equator. Therefore, gold will weigh less at the equator and Amit's friend will not agree with the weight of gold bought.
