Quizplus · Accepted Answer

The mass of the building does indeed exert a gravitational pull on objects (including people) within or close to it, which can slightly counteract the Earth's gravitational pull, making a person weigh less. This effect is very small but is a direct consequence of the gravitational attraction between masses according to Newton's law of universal gravitation.
