Answer:
Amit's
friend does not agree with the weight of gold bought.
Reason: The acceleration due to gravity on the surface of the
earth is given
by
Since G and M
are constants
The radius
(R) of the earth is not the same everywhere. This is because of the shape of
the earth which is not perfectly spherical. It is slightly flattened at the
poles and bulges at the equator. Therefore, the value of g on earth is maximum
at the poles and minimum at the equator. Thus, the weight of gold will be
greater at the poles than at the equator.
