Question

if someone living at Antarctica buys gold from the countries near equator and then. sells at Antarctica .By this way he would become rich . But is this possible ?

Answer 1

The value of 'g'(acceleration due to gravity) is greater at the poles than at the equator. This is a fact. This is due to the cancellation of gravity of the Earth and the centrifugal force.

So suppose 1 kg gold at a price of 1 crore is bought at the equator.Now the gold is taken to the poles. Now since 'g' is higher at the poles. The same 5kg gold would weigh more than 5kg.(Weight=m*g) here.Assuming the price to be same, one would get a higher price by selling gold at poles. So one can become richer by selling gold at the poles.
