Question

explain why 1 kg of gold would weigh different at the poles and equator​

Answer 1

1kg. of gold would weigh different at the poles and equator, since the Earth is not exactly spherical. It bulges out more at the equator and is flattened at the poles. Thus the distance from the centre of earth will be higher at the equator than the poles. Therefore, the gravitational pull experienced experienced at the equator will be lower than that of poles. Thus 1kg of gold would weigh more at the poles than the equator
