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 weigth of gold bought? If not, Why? Hint: The value of g is greater at the poles than at the equator.]

Explanation

Weight differs from poles to the equator.
W = m `xx` g
W `infty` m
W `infty` g
at
Ploes `W_(p) = m xx ` g
Equator `W_(e ) = m xx g `
Weight of gold at equator is less than weight poles
