We know , weight W = mg; Here m = mass of the object and g = gravitational acceleration. The mass of an object is a constant quantity , so the weight of the object in the corner depends on the gravitational acceleration. Therefore, the weight of the object varies due to gravitational acceleration. The higher the gravitational acceleration , the higher the weight of the object. And the lower the gravitational acceleration, the lower the weight of the object. For example , gravitational acceleration is higher in the polar region. Thus the weight of the object is higher in the polar region.
