If you stand at rest on a weighing scale and find that you are pulled toward Earth with a force of 500 N, then the normal force on the scale is also N and you weigh N. How much does Earth weigh? If you tip the scale upside down and repeat the weighing process, you and Earth are still pulled together with a force of N, and therefore, relative to you, the whole 6 x 10^24 kg Earth weighs N
